Benfica winger Franco Cervi is being tracked by Premier League clubs ahead of the summer market.
The Sun says Newcastle, West Ham, Brighton and Swansea are all tracking the £20million-rated Argentine.
Cervi is enjoying a great season with Benfica but is keen to make a move to England this summer.
He has started 27 of the Portuguese league leaders' 31 top-flight games this season.
Cervi has also played in the Champions League and was linked with a move to German giants Borussia Dortmund last year.
