The Atletico Madrid man, currently on duty with the Spanish Under-21 side at the European Championships, is widely thought to be the man United boss Sir Alex Ferguson has pinpointed to replace the retiring Van der Sar.

A fee of £18million has been mentioned for the 20-year-old, but he claims that does not interest him and that if he does move to Manchester, he will only be concerned with ably filling Van der Sar`s boots.

"I feel incredibly motivated by the fact that Manchester United are thinking about me," he said.

"I like the fact that they are considering me as a replacement for a goalkeeper of Edwin van der Sar's calibre.

"I will need to keep on striving and working hard, as I am still in the outset of my career, and I still have much to do at this level.

"I hope I will still be playing when I am his age. It is hard to look so far ahead but it is something I want to do.

"The fact that I could become one of the most expensive goalkeepers ever does not interest me. The value that really counts is what you do on the pitch."
