The Footballers' Football Show lifted the lid on the complex world of fitness coaching on Monday night.
Host David Jones was joined by Jon Goodman, Ryland Morgans and Tony Strudwick who look after the physical conditioning of players at Leeds, Liverpool and Man United respectively.
And the panelists discussed how they prepare their players for the exertions of modern-day football.

Match day process
TONY STRUDWICK: We work the week around th kick-off time. An earlier kick-off is always tougher because the players are out of synchronisation because they have to get up at different times and they have to get their pre-match feed in three and a half hours before a game. So we provide a template for whether it's a 12.45pm start, a 4pm kick off or an evening game."
RYLAND MORGANS: If we had an early kick-off we'd have the players in a local hotel in Liverpool to make sure they're eating the right things at the right time. Certainly in the Premier League, players are in hotels for home and away games to ensure they are getting to bed when they need to. That's on the premise, not that they're unprofessional, but that players may have young children keeping them up at night which can impact on how they prepare for the next day. Ultimately their food timings can be out because of that as well."
GPS tracking in football
GOODMAN: No day during the week is the same for us preparing the players for a match, but within that you may have different players with different needs. It's really important for us to gather information about the players - especially new players - because the more information we can gather the better decisions we can make about individualising the training and preparing the players.
Data on distances covered
STRUDWICK: The critical metrics we look at are the high-intensity work because that's the more fatiguing work, as opposed to the background running, which is the total distance covered. We'd look at the number of sprints but it's about putting it into context. Each player would have their own physical profile and the important thing for us is to establish what's the player's norm and when they're working above or below their average.
