The 26-year-old only arrived on Merseyside over the summer in a £7m deal from Celta Vigo, but already looks set to struggle to establish himself at Anfield.
Aspas had an impressive record in his homeland, with his 12 goals in 33 appearances in Spain’s top tier last season earning him much praise.
The versatile forward started the season as a key man under Brendan Rodgers, but the return of Luis Suarez – who has formed a deadly partnership with Daniel Sturridge – and niggling injuries seem to have hampered his chances of becoming a first-team regular.
Aspas has failed to find the back of the net in his six games for Liverpool so far, which has led to rumours that the Reds are ready to cut him loose.
Betis are thought to be ready to offer him a route back to his home nation, and are hopeful that the lure of returning to familiar surroundings may be enough to tempt the player to call time on his career in England.
However, Rodgers may be unwilling to let Aspas leave over the winter, with Sturridge’s injury woes having left him short on support for Suarez.
Valencia – who rivalled Liverpool for the attacker’s signature during the last window – are also keen.
