West Ham United boss Sam Allardyce has dismissed the moaning from his sports science staff.
Allardyce has revealed how most of his players are refusing to leave the training field when his sessions end and that he is at loggerheads with his sports science team, who worry over the amount of work the players are doing on a daily basis.
"That is a nice feeling for me, when all of a sudden the players want to stay on the training pitch when you have blown the whistle," said Allardyce. "It was not like that when I first came - the players wanted to get straight off and get out of here.
"That is a great indicator for me, because it tells me they enjoy being here.
"Sports Science [staff] will run up to you and say, 'Gaffer, get them off' and 'They are doing too much.' I just say, 'Shut up.'
"They always do that, but I say if they want to do something on their own, just leave them to it. If they carry on too long, we will keep an eye on them.
"The sports science [staff] and coaches will tell me what they think we should do but, at the end of the day, I will make the final decisions.
"Sometimes when they don't like it they have to lump it."
