Owen Hargreaves has said that Fulham manager Felix Magath makes his players work too hard during training.
The former England international played under the German during his spell in charge at Bayern Munich from 2004 to 2007.
The retired midfielder told BT Sport: "He definitely does that. I can guarantee you he's running them into the ground, that's standard procedure.
"At times we would have a game, pre-season, in the evening and we'd be doing stairs in front of the top players. The lads had won Champions Leagues and we'd be thinking, 'what's going on here?'
"But that's his philosophy, it's medicine balls, it's running. We used to do full-length sprints holding medicine balls. The sport scientists would be having a heart attack watching that nowadays, but that was just his regime. He came from that era. That's the way he knows to prepare players and there's no way it's going to work in this country. Impossible."
Fulham sit at the bottom of the Championship table with no wins from their opening four matches of the season.
