Ferdinand, who has not featured in the last two winless games, lays the blame squarely at the door of the new boss as the players try to adjust to life after legendary boss Sir Alex Ferguson who stepped down in the summer.
He told BT Sport: "This manager is a bit different in that he doesn't name the team beforehand, you don't get to know the team.
"The old manager used to give you a little bit of an idea if you were playing.
"When you know you're playing the intensity goes up a little bit I'd say.
"That's what you've got to try and do even if you're not sure if you're playing, get to that intensity.
"It's hard to do mentally. You spend a lot of nervous energy thinking 'am I playing, am I not playing'.
"Keep just going round in circles in your head, enough to turn you into a mad man."
