Manchester City right-back Micah Richards has revealed the intensity of training has increased since Manuel Pellegrini arrived at the Etihad Stadium.
The defender - who missed City's first six games of the season due to a hamstring injury - believes training sessions have improved under the Chilean tactician.
Richards made his comeback in Manchester City's 5-0 win over Championship side Wigan Athletic in the Capital One Cup.
And Richards, speaking before City's impressive win, said on Pellegrini's managerial style: "I think pre-season took its toll because we had a lot of games and there was a lot of travelling, and whereas some of the guys are fine, being a bigger lad, it takes my body maybe a couple of days longer to recover.
"Under Roberto Mancini, the intensity in training was a little lower - that's not a criticism of Manuel Pellegrini's methods - it's just that the workload has increased and it's going to take the players time to get used to it.
"We'll get used to it and ultimately it's to our benefit because we'll get fitter and stronger as time goes on."
Richards faces a battle to hold down a regular starting spot in Pellegrini's line-up with the likes of Vincent Kompany, Matija Nastasic and Pablo Zabaleta impressing at right-back during his prolonged absence from action.
The England international was a regular at right-back during City's title-winning season and Richards wants to concentrate on winning back a full-back slot.
He added: "We have some great central defenders at this club with Vinnie (Kompany), Matija (Nastasic) and Joleon (Lescott) and we also have Martin Demichelis now, too, so I can't see a time where I'll really get a good run in central defence.
"I think right-back is where I need to concentrate on playing for the time being."
