Nicolas Gaitan will cost any interested clubs £21million according to recent reports.

According to the Daily Mail, Benfica have valued the 27-year old attacking midfielder at the aforementioned amount as top European clubs begin to circle.

Liverpool are believed to be showing significant interest in Gaitan while Manchester United have long been linked with the Argentine.
