Manchester United chief executive David Gill has insisted that Cristiano Ronaldo is not for sale.

The future of the Portuguese winger has been the subject of intense speculation in recent weeks after he admitted he would like to play for Real Madrid one day.

Asked if United would be keeping hold of their most prized asset, Gill said: “Without doubt we are.

“He’s got four more years (on his contract) until 2012, he’s been with us for five years and we’re sure he’ll be with us for many years to come.

“He’s clearly one of the best players in the world and he’s at a great club, winning trophies.

“He enjoys it immensely here, you can tell that when you speak to him privately. Why would he want to leave?

“We have no intention of letting him go, we will make sure that he’s very happy here, as we do with all our top players.”

Reports have suggested that United’s debts currently stand at £764million, but Gill is adamant that Ronaldo will not sacrificed to reduce that figure.

“Manchester United is not a club that sells its main assets,” he told Radio Five Live.

“In order to service our debts we need a very successful team on the pitch, and you don’t achieve that by selling Cristiano Ronaldo.”
