315: The Under-fueling Problem in Professional Sport with Dr Nessan Costello

Science for Sport — Mon, 13 Apr 2026 06:00:00 +0100

Sports nutrition in elite football is often misunderstood, even by the players doing it for a living. In this episode, Richard Graves sits down with Dr. Nessan Costello, 1st Team Sports Nutritionist at Al-Ahli in the Saudi Arabia Pro League, to cut through the noise and get practical about what performance nutrition actually looks like at the highest level.
Nessan has worked across the Premier League with clubs including Chelsea, Newcastle United and Leeds United, and brings a rare combination of academic rigour and real-world experience to the conversation. From fuelling strategies across a congested fixture schedule to navigating Ramadan with Muslim players, and from debunking carbohydrate myths to calling out the damage done by overly controlling nutrition environments, this is a frank and refreshingly honest look at what it takes to keep elite footballers performing at their best, week in, week out.
Whether you're a practitioner working at the sharp end of elite sport, a coach trying to get more out of your athletes, or simply someone who wants to understand the science behind peak performance, there is plenty here for you.

In This Episode You Will Learn

Why the majority of elite footballers are chronically underfuelled — and why that matters more than their body fat percentage
The real science behind carbohydrate loading: why you should start 24 hours before kick-off, not the night before, and what foods actually work
How to structure post-match nutrition across a 72-hour recovery window, including the specific gram-per-kilogram targets Nessan uses with his players
Why ultra-lean body composition as a performance goal is actively harming players, and how disordered eating behaviours are more common in elite football than most environments will admit
How Nessan adapted his approach during Ramadan — including training sessions at 10pm and cup semi-finals kicking off at 1:30am
The practical hydration framework he uses: why 500ml of fluid with every meal beats carrying a big bottle around all day
How nutrition changes across a full season, from pre-season heat acclimatisation through to the demands of a congested run-in
Why supplements are largely irrelevant until you've nailed sleep, three meals a day, two snacks and consistent hydration
What working in the Saudi Pro League has taught him about personalised nutrition across diverse nationalities and food cultures
His advice for coaches and practitioners working without a dedicated nutritionist — and when it becomes worth bringing one in

312: The Role of Environment in Player Performance

Science for Sport — Mon, 23 Mar 2026 06:00:00 +0000

This week on the Science for Sport podcast, Richard Graves is joined by former professional footballer Carl Asaba for an honest and insightful look at life inside the game.
Carl’s journey into professional football wasn’t typical. From missing out on early opportunities and stepping away from the game, to earning a contract at 21 and going on to play over a decade in the professional ranks, his story challenges many of the assumptions around talent pathways and development.
Across the conversation, Carl reflects on the psychological demands of elite sport, handling pressure, navigating setbacks, and the importance of environment and culture in performance. From record transfers and dressing room dynamics to playoff heartbreak and career-defining moments at Wembley, this episode offers a grounded, real-world perspective on what it actually takes to build and sustain a career in football.
For practitioners working in elite sport, there are clear takeaways around player psychology, team culture, and the often-overlooked role of man management in performance.

In this episode, you will learn

Why non-linear talent pathways can still lead to elite performance
How early setbacks can shape long-term motivation and resilience
The psychological impact of transfers, expectations, and identity
What separates strong team cultures from individual-driven environments
Why “man management” remains a critical performance skill in modern sport
How players experience pressure in high-stakes matches (e.g. playoffs, Wembley)
The role of belief, environment, and coaching in unlocking performance
Lessons on handling success, ego, and distractions early in a career
What burnout, injury, and time out of the game really feel like
Why giving “your all” is a more sustainable mindset than chasing outcomes

About Carl Asaba
Carl Asaba is a former professional footballer whose career spanned over a decade across English football. Starting his professional journey at Brentford at the age of 21, he went on to play for clubs including Reading, Gillingham, and Sheffield United.
Known for his work ethic and team-first mentality, Carl was part of some iconic teams, including Gillingham’s promotion-winning side and Sheffield United’s memorable 2002–03 campaign, which reached the latter stages of multiple competitions.
Since retiring, Carl has remained close to the game through media work and supporting the next generation, while offering a unique perspective shaped by both traditional and unconventional routes into elite sport.

305: Building Resilient Athletes in High-Pressure Environments

Science for Sport — Mon, 02 Feb 2026 06:00:00 +0000

Behind every high-performance environment are people, personalities, and decisions that shape outcomes. This week on the Science for Sport Podcast, Richard Graves is joined by former England international and Premier League defender Warren Barton, speaking from California.
Warren reflects on a career that spanned very different eras of elite football, from coming through non-league and the famously demanding culture of Wimbledon’s “Crazy Gang”, to becoming a record signing at Newcastle United during the Entertainers era. Across the conversation, Warren offers a rare, first-hand perspective on the psychology of professional sport: rejection, resilience, team identity, leadership, and how elite environments shape behaviour.
The discussion also moves into modern high-performance sport, exploring how man-management, culture, and trust still sit alongside data, technology, and sports science. Warren shares thoughtful insights on coaching, communication, player wellbeing, and why asking an athlete how they feel still matters just as much as what the numbers say.
A wide-ranging, honest conversation that will resonate with practitioners working in elite sport, as well as those interested in the human side of performance.

In this episode you will learn

How early rejection and non-academy pathways can shape resilience and long-term success
Why strong team culture and shared identity can create psychological advantages over more talented opponents
Lessons from Wimbledon’s “Crazy Gang” environment and what modern teams can still learn from it
How elite managers like Kevin Keegan, Kenny Dalglish, and Sir Bobby Robson differed in leadership and man-management
Why man-management remains central to performance, even in data-rich environments
How elite players and coaches balanced intuition, experience, and emerging sports science practices
The importance of trust, togetherness, and players “having each other’s backs” in high-pressure environments
Where modern football may be losing connection with basic human communication
Warren’s perspective on technology, VAR, and how decision-making affects the athlete and fan experience
How coaches can better integrate data with athlete feedback and lived experience

About Warren Barton
Warren Barton is a former England international footballer who played at the highest level of English football during the 1990s. His career included spells at Wimbledon and Newcastle United, where he became part of Kevin Keegan’s iconic “Entertainers” side and captained the club during one of its most influential Premier League eras.

297: Finding the Competitive Edge: Elite Performance with FC Midtjylland’s Niklas Virtanen

Science for Sport — Mon, 08 Dec 2025 06:00:00 +0000

This week, host Richard Graves sits down with one of the most energetic and thought-provoking voices in modern performance: Niklas Virtanen, Head of Sports Science at FC Midtjylland.

If you’ve ever wondered how a club without the financial muscle of Europe’s giants consistently outperforms bigger teams, beating Nottingham Forest away, winning at Celtic, and challenging at the top of the Danish Superliga, this conversation tells you exactly how they do it.

Niklas is a rare blend of passion, creativity and evidence-based practice. His presentation at a recent Catapult event had the entire room hooked, and this episode delivers the same energy. From dismantling traditional GPS limitations to redefining how football teams train for micro-actions, set pieces, and physical dominance, Niklas pulls back the curtain on the processes driving Midtjylland’s success.

This episode goes deep into the real-world application of sports science, the balance between data and intuition, and why sometimes the most powerful competitive advantage is simply learning to “solve problems without money.”

Things You Will Learn

Why FC Midtjylland’s entire model is built on “solving problems without money” and how data gives them a competitive edge.
How Niklas and his team dominate set pieces using Trackman technology and detailed ball-flight analytics.
Why GPS alone is blind to football’s most important movements, and how inertial data captures the micro-actions that matter.
How to use accelerometers, gyroscopes and magnetometers to measure real football movement quality.
The truth about injury “prediction,” why we still don’t know athletes’ limits, and why subjective data is often your most valuable input.
How to balance analytics with player feelings, coaching intuition, and the “eyeball test.”
Why communication, not technology, is the biggest challenge when coaching staffs change.
Practical ways to design training exercises that actually transfer to match actions (including why traditional rondos may be overrated).
How to create buy-in across departments in fast-moving environments with shifting coaching teams.
Why the best decisions come from leading with data first, then layering coaching opinions on top.

About Niklas Virtanen
Niklas Virtanen is the Head of Sports Science at FC Midtjylland, one of Europe’s most forward-thinking football clubs and pioneers in data-driven performance.
From Finland’s Jyvaskyla to the top of the Danish Superliga, Niklas has carved out a journey defined by curiosity, relentless learning, and a willingness to challenge traditional methods. Starting his career as a physiotherapist, he transitioned into coaching, performance, and ultimately sports science — where he discovered his passion for practical, applied, football-specific methodology.
At Midtjylland, Niklas plays a central role in integrating data, performance analytics, inertial technology and coaching processes. His approach blends scientific rigour with real-world applicability, always anchoring decisions in the question: “Does this help the players perform?”
He collaborates closely with coaches, mental performance staff, physios, analysts, and leadership teams, shaping a holistic performance culture built around trust, objective data, and constant communication.
Niklas is known across the professional football community for his high energy, creativity, authenticity, and his commitment to pushing the boundaries of what sports science can be. You’ll often find him speaking to — and learning from — industry leaders such as Chris Barnes and Paul Balsom, who he credits with encouraging him to explore unconventional ideas, test them in the real world, and build evidence from the ground up.
He shares many of these insights on LinkedIn, where he’s become a respected voice for modern performance practitioners.

284: Club Plans & Personal Coaches: Adding An Edge?

Science for Sport — Mon, 08 Sep 2025 06:00:00 +0100

Club Plans & Personal Coaches: Adding An Edge?

In this week’s episode, host Richard Graves sits down with Daniel Booth, a performance coach who’s worked inside elite teams (Watford FC, Ealing Trailfinders), across Olympic sprint programmes, and independently with top athletes, to unpack one of the hottest debates in high performance:
Should athletes stick strictly to club schedules, or can personal trainers/physios/dietitians add an edge without adding risk?

Drawing on experience from football, rugby, and Olympic sport, Daniel explains why tensions flare (mismatched philosophies, poor communication, asset ownership), what great collaboration looks like in the real world, and how high-performing organisations formalise outside support without losing control.

What you’ll learn

The real source of conflict between club performance/medical staff and external coaches, and how cross-sport thinking challenges “that’s how we’ve always done it.”
A practical collaboration model: who shares what, when, and how (weekly data drops, post-match/flight recovery notes, and a single “central coordinator” to integrate inputs).
Risk vs. reward in load management: why living on the “edge” drives adaptation, and how to avoid double-loading athletes after intense sessions.
Contracts done right: how some teams formally write approved externals into player agreements and set clear, shared calendars.
International duty realities: why centralised models in rugby/cricket often outperform football’s fragmented approach, and what football can copy now.
Case studies that translate: lessons from LeBron/Mancias and Mahomes/Stroop—how season-long regen blocks and role clarity reduce noise and improve availability.
Social media pitfalls: why chasing a “brand” erodes trust, and how word-of-mouth and discretion still win in elite environments.

About Daniel Booth
Daniel Booth is a performance coach with 10+ years’ experience across elite football (Watford FC), rugby (including Ealing Trailfinders), and Olympic sprint programmes, as well as work with Warner Bros. Discovery. Now operating independently, he partners with clubs and national teams to deliver athlete-centred programming and is formally written into several Premiership rugby player contracts to act as the central performance coordinator, integrating club, country, and external inputs. Daniel’s approach blends cross-sport best practice, honest communication, and low-ego, data-led decision-making focused on availability and longevity.
