Manchester City's designate chairman Khaldoon Al Mubarak says manager Mark Hughes will have final say on all transfers.
He told the club's website: "One thing I have made very clear to Mark is that any player he wants comes from him.
"I am not an expert. It is Mark who runs the club and Mark who makes the football decisions.
"We are here to support and make financial decisions, but we are not here to teach Mark or Garry (Cook) what to do.
"They are the professionals, we trust them, we have confidence in them and we are going to support them.
"Mark is an honest man, he's a leader, he's tough and he is everything you would want in a head coach. We trust him, he's one of the gems we saw in this club once we came here.
"He will put a plan together to win trophies, but we will be patient. As long as it is being managed properly and the players are doing what they need to do, then it will take whatever it takes."
