The 26-year-old has struggled to settle on Merseyside since his big-money move from Celta Vigo last summer and the Spanish giants have contacted the Reds over his availability.

Aspas, who netted 12 times in La Liga last season, struck his first goal for Liverpool in their recent FA Cup win against Oldham at Anfield.

The form of Luis Suarez and Daniel Sturridge, coupled with a thigh injury, has restricted Aspas' first-team opportunities and Valencia boss Juan Antonio Pizzi could look to tempt him back to his homeland with the lure of regular football.
