The 28 year old joined Zaragoza in 2006 from Valencia where he had spent the majority of his career. After Rafa Benitez came to Anfield it was widely speculated that Aimar would soon follow, however a move never materialised for the Argentine international.
He is back in the headlines again this week now linked with a move to St. James Park. After the departure of Emre, Newcastle are on the hunt for a creative and pacey midfielder, and Aimar could be the answer to their problems. It is likely that he could cost the Geordies up to £7 million.
Personally I think that he would be a great signing for Keegan, although I feel he should concentrate on their defensive issues first, a good start in doing so would be signing Richard Dunne from Man City.
