The 22 year old is currently attending Euro 2008 with Spain, where his performances have obviously reignited Rafa Benitez' interest in the player after missing out on him last year. Although his form in front of goal doesn't look to promising, his services on either wing would surely be much appreciated at Anfield.
Personally as a Liverpool fan I think that signing a quality winger should be our number 1 goal for the Summer, and the likes of Silva or David Bentley would fit in perfectly in Rafa's regime.
