Swansea City are chasing PSV Eindhoven fullback Santiago Arias.
The Colombia international is expected to be on the move this summer.
Swansea are preparing an €8 million offer for Arias, which would rise in bonuses based on appearances and success.
Arias' deal includes a 15 per cent sell-on clause for former club Sporting CP.
The defender is ready to leave as he seeks to make a new step in his career.
