With Ronaldo facing United for the first time since his £80m move in 2009, speculation linking the attacker with a move back to Old Trafford has been rife.
Talk of a collaborative effort between the club and sponsors Chevrolet to put together a financial package has further fuelled speculation, but according to Sir Alex such a move is unlikely and perhaps the work of his agent:
“There hasn’t been anything to encourage me to think Cristiano would come back here.
“As far as I am aware, there is nothing in it at all. Ronaldo has got two years left on his contract and it seems to me it is all part of the negotiations that are going on about a new deal.
“Maybe his agent is playing the game. I think it is false hope. Cristiano will get a good reception. All our former players, especially the ones who have been great for this club, get a good reception when they return.”
