Podcast Overview: Jack Sharkey on Football Performance, Sport Science and Why Data Isn’t Enough

In this episode, we sit down with Jack Sharkey, Director of Performance, to explore the reality of working in football performance.

Jack’s career has taken him through Burton Albion, QPR, Aston Villa, the Australian national team and Olympique Lyonnais. Across that journey, he has worked in lower-league football, the Championship, the Premier League, World Cup environments and Champions League football.

This conversation goes beyond GPS, data and gym work. Jack reflects on coming out of university with academic knowledge, then learning quickly that football demands something different: communication, trust, reliability, simplicity and the ability to make performance work useful to coaches and players.

We discuss the importance of lower-league experience, working with different managers and players, the politics of football clubs, the demands of international football, and what it takes to lead a multidisciplinary performance department.

The central message is clear: data is not enough. Football now has more information than ever, from GPS and video to AI and dashboards. But unless practitioners can translate that information into football language, it risks becoming noise.

For coaches, sport scientists, analysts, psychologists and performance staff, this episode is about keeping performance work connected to the game.

What you’ll take from this episode:

* The reality of working in football sport science

* Why trust, communication and reliability matter

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

* Why data must be translated into football language

* The danger of specialists drifting away from the game

* How performance departments can support better decisions
