Tottenham boss Mauricio Pochettino won't relax his tough training methods.
Pochettino wants his Tottenham players to get even fitter in 2015.
Pochettino's exacting training methods have tested the resolve of the Spurs squad but it appears they are now seeing the benefits. Statistics indicate that the team are running, on average, three miles more per game than they were last season.
"You can always improve in all areas and I have never set a limit," said the Spurs head coach. "As with tactical situations, you can always improve your physical condition and you can always do better every day.
"That is our challenge: never to stop working, and after that we will see where the limit is. It is difficult to know whether there is another team in better condition than us. Because we don't have access to certain statistics, it is something you sense only at the start of a game."
