The long-running saga over Real Madrid's desire to sign Chelsea's Dutch winger Arjen Robben took another twist last night when president Ramon Calderon claimed the deal now hinged on the London club's willingness to do business.

They have been closely linked with Robben throughout the summer but have failed to persuade Chelsea to part with the player even after the Londoners added Lyon winger Florent Malouda to their squad.

The 23-year-old was in the process of negotiating a new four-year contract at Stamford Bridge but there are increasingly ominous signs that it is now only a matter of time before Madrid finally get their man.

Calderon said: "We are advancing in the negotiations. Those responsible are doing it very well, and I hope that it comes to fruition.

"But until the agreement is closed we cannot say anything. It has to be the selling club who first decides, and once that has happened, I don't suppose there will be any problems resolving the player's contract."

Chelsea coach Jose Mourinho wants Robben to stay and sign a new deal but the Dutchman, who is represented by his father Hans, will move on if the English club decide it would be better to cut their losses.
