David De Gea 'motivated' by potential Manchester United switch

David De Gea claims he is not worried about the possibility of becoming one of the world's most expensive goalkeepers if he joins Manchester United, and is only concerned about being a worthy replacement for Edwin van der Sar.

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."
