"I see similarities between them," Butt told the Sunday Sun of Allardyce and Ferguson. "You definitely know who's boss here, as you do at United.
"He's the man everyone looks up to, and when he walks onto the training pitch everyone steps up a level.
"The set-up here now is also similar to Old Trafford. The manager and the staff there were always 100 per cent every day in training, and the gaffer is obviously trying to promote that here.
"He's obviously a no-nonsense manager. From an outsider's view looking in on his time at Bolton, he looked like a tough man to play for and would take no crap, and I'm sure he'll be the same here.
"He's come in, set up a whole new regime, with new training methods and an emphasis on dedication and commitment. He's made it clear that no player here can take anything for granted."
