Manchester United midfielder Marouane Fellaini admits there's no slacking off even at this stage of the season.
Fellaini revealed Van Gaal, a stickler for time and discipline, blew his top at a group of his squad and issued on the spot fines.
He said: "He blew a fuse the other day when a group of 10 of us were one minute late for lunch after training.
"You think one minute is nothing and it wasn't for training, but for the canteen. For him it's important though.
"He dished out a few fines. That's what happens to late-comers and even for a red card. You get fined, too, for a bad foul."
