Liverpool are threatening Swansea City's deal for Jonathan de Guzman.

De Guzman has been a revelation for Swansea this season, playing his way into the Holland squad after arriving on-loan last summer from Villarreal.

However, Swans boss Michael Laudrup has stalled on wrapping up a permanent deal for De Guzman, so opening the door for Liverpool.

Spanish transfer market experts says Villarreal have been approached by Liverpool representatives to register their interest in De Guzman.
