Manchester City boss Mark Hughes will have no problems with new signing Craig Bellamy having a pop at his new teammates.
Hughes said: "Craig is a winner and he wants to be the best he can be.
"He is demanding of himself and demanding of the staff he works with and of his team-mates, but that is not a bad trait to have.
"And I encourage it because I think that players of that ilk are good for your club.
"I have worked with Craig for many years. I understand his personality and I have great respect for his ability. And he has matured over the years."
