Manchester United chief executive David Gill insists Cristiano Ronaldo will not be sold.
Real Madrid are interested in the Portuguese star, but Gill said: "There is no interest or appetite in selling Cristiano for whatever amount of money offered.
"It has never been discussed. Everything about him is Manchester United, he's like George Best and Eric Cantona. You can't sell players like that.
"We've never sold a player that Sir Alex Ferguson has wanted to keep. We don't need to. There's no financial requirement."
