Manchester United midfielder Morgan Schneiderlin said he is having to adapt to the "very strict" coaching style of Louis van Gaal.
Schneiderlin moved to Old Trafford this summer after seven years at Southampton, in which time he worked under eight different managers, including Nigel Adkins, Nigel Pearson, Alan Pardew, Mauricio Pochettino and Ronald Koeman.
"Van Gaal is a very strict coach. It's a new management approach, one I haven't experienced before. You have to adapt because a lot of things have changed," Schneiderlin was quoted as saying by Telefoot on Sunday.
The 25-year-old said he is enjoying his time at the club, "Manchester United are the greatest club in the world. You can see it in the enthusiasm among fans when we play a game."
Schneiderlin's compatriot Anthony Martial, meanwhile, has promised to try to repay the huge transfer fee United splashed out to sign him on transfer deadline day.
The 19-year-old Frenchmen, who signed for 36 million pound has grabbed the headlines already having started his time in England with four goals in five matches.
