ISSPF Soccer Insights Podcast Episode #3 with Jack Sharkey

Football Performance, Sport Science and Why Data Isn’t Enough

The International Soccer Science & Performance Federation is proud to announce the launch of Episode 3 of the ISSPF Soccer Insights Podcast, featuring Jack Sharkey, Director of Performance, in a powerful discussion on football performance, sport science, data, communication and the realities of working inside professional football clubs.

This new episode, titled “Jack Sharkey on Football Performance, Sport Science and Why Data Isn’t Enough”, explores one of the most important questions in the modern game:

What does it really take to make sport science useful inside a football club?

In today’s football environment, clubs have access to more information than ever before. GPS data, player tracking, video analysis, AI, Power BI dashboards, wellness scores, load monitoring, recovery metrics and performance reports are now part of everyday practice across the professional game. But information alone does not improve performance.

The real challenge is turning data into decisions.

That is the central theme of Episode 3 of the ISSPF Soccer Insights Podcast, where Jack Sharkey shares his experiences across professional football, international football and elite women’s football, offering valuable lessons for coaches, sport scientists, analysts, strength and conditioning coaches, psychologists, medical staff and performance leaders.

Jack Sharkey – A Career Across the Professional Game

Jack Sharkey’s journey through football performance has taken him across a wide range of environments, levels and cultures.

His career has included roles with Burton Albion, QPR and Aston Villa, as well as international football with Australia and elite women’s football with Olympique Lyonnais. Across that journey, Jack has experienced League Two, League One, the Championship, the Premier League, World Cup environments and Champions League football.

That breadth of experience gives this episode real depth.

Rather than focusing only on elite-level structures, Jack reflects on how important the lower-league environment can be for developing practitioners. Early experiences at clubs such as Burton Albion helped him understand that sport science in football is not about showing how much academic knowledge you have. It is about learning how to help.

That message will resonate with many young practitioners entering the game. University education provides important foundations, but the reality of football is different. The dressing room, the manager’s office, the training pitch, the treatment room and the match-day environment all teach lessons that cannot always be found in textbooks or research papers.

Why Data Alone Is Not Enough

One of the key messages from the episode is simple:

Data is not enough.

Football now produces endless information. Sport scientists and analysts can collect data on total distance, high-speed running, sprint distance, accelerations, decelerations, metabolic power, training load, heart rate, wellness, fatigue, recovery and tactical behaviours. Technology has changed what clubs can measure and monitor.

However, Jack explains that the value of data depends on how it is communicated and used.

If a coach cannot understand the information, it becomes noise. If a player cannot connect the feedback to their role, it has limited impact. If a performance department produces reports that do not influence decisions, then the process becomes disconnected from the game.

This episode challenges practitioners to think carefully about how they present information. It is not enough to collect more data. The best sport scientists and performance staff must translate information into football language. They must understand the game, understand the coach, understand the player and understand the context.

Good performance support is not about producing the most complicated dashboard. It is about helping the club make better decisions.

Trust, Communication and Reliability

Throughout the episode, Jack returns to the importance of trust, communication and reliability.

In football clubs, relationships matter. Coaches need to trust that the performance staff understand the demands of the game. Players need to trust that the information they receive is useful and relevant. Managers need practitioners who can communicate clearly, work within the hierarchy of the club and support decisions without overcomplicating the process.

Jack reflects on the reality that some of the most important skills in football performance are not technical skills. They are human skills.

Can you communicate clearly?
Can you build trust with a manager?
Can you support players without overwhelming them?
Can you understand when to speak and when to listen?
Can you present information in a way that supports decisions rather than creating confusion?

These are essential qualities for modern sport scientists and performance practitioners.

For those studying football sport science, strength and conditioning, performance analysis or high-performance coaching, this is a critical lesson. Knowledge matters, but delivery matters just as much. The best practitioners are not always those who know the most. They are often those who can make complex information simple, relevant and useful.

Lessons from Burton Albion, QPR, Aston Villa, Australia and Lyon

A major strength of this episode is the range of environments discussed.

Jack shares lessons from Burton Albion, where early exposure to professional football helped shape his understanding of hierarchy, communication and the daily realities of club life. Working in lower-league football often requires adaptability, humility and problem-solving. Resources may be more limited, but the learning can be incredibly powerful.

The conversation also moves through experiences at QPR and Aston Villa, where Jack reflects on different player journeys, football politics, standards and the challenges of supporting players across varied career stages. These environments highlight the need for performance staff to understand people as well as numbers.

International football with Australia brings another layer to the discussion. Tournament environments, World Cup preparation and working with international staff groups create different demands. Time is limited, communication must be clear and every decision matters.

Jack also discusses his work with Olympique Lyonnais, one of the most successful clubs in elite women’s football. This section explores leadership, multidisciplinary departments, French football culture, elite standards and the role of a Director of Performance in creating alignment across staff groups.

Together, these experiences provide a valuable insight into the modern football performance environment.

Keeping Sport Science Connected to the Game

One of the most important warnings in the episode is the danger of specialists drifting away from football.

As the game becomes more advanced, there is a risk that departments become too focused on their own specialist areas. Sport science, data, analysis, medicine, psychology, nutrition and strength and conditioning all play important roles. But each area must remain connected to the game itself.

Football performance is not built in isolation.

The best performance departments understand the tactical demands of the team. They understand the coach’s playing style. They understand the match schedule, the training week, the player profiles and the psychological demands of competition.

Jack’s message is highly relevant for modern practitioners: do not become detached from football. Data must support the game. Sport science must support coaching. Technology must support better decisions. Performance departments must help players and teams perform, not simply produce information.

What Coaches and Practitioners Can Learn

Episode 3 of the ISSPF Soccer Insights Podcast offers clear lessons for anyone working in football or developing their knowledge in soccer performance.

Coaches will gain insight into how performance staff think, communicate and support the training process. Sport scientists will be challenged to think beyond numbers and consider how their work influences decisions. Analysts will recognise the importance of translating information into game understanding. Strength and conditioning coaches will see how physical preparation must connect with the tactical and technical demands of football.

The episode is also highly relevant for students and early-career practitioners. Jack’s reflections show that progression in football is not only about qualifications or technology. It is about reliability, humility, communication, trust, adaptability and a willingness to understand the environment.
