Bolton Wanderers defender Marcos Alonso is on Swansea City's radar.

The Daily Mail says Swansea City are interested in Alonso.

The 22-year-old has been restricted to seven games this season after Stephen Warnock came in on loan from Aston Villa.

Alonso is a friend of Swansea manager Michael Laudrup's son, Andreas, who was a youth player at Real Madrid with Alonso.
