Antonio Adan is having an impressive campaign at Real Betis Getty.

Liverpool are considering a summer swoop for Real Betis sensation Antonio Adan after discovering "a bargain €8m [£6.2m, $8.9m] release clause" in his contract, according to AS. The Spanish publication claims the former Real Madrid academy goalkeeper has attracted the attention of a number of Premier league outfits, following an impressive campaign that could even see him called up to the Spanish national team for Euro 2016.

The 28-year-old custodian is perhaps best known for his role in Jose Mourinho's final days at the Santiago Bernabeu, when the Portuguese boss controversially handed him the number one role ahead of club legend Iker Casillas.

Mourinho's put the player under scrutiny by Casillas's loyal fans, forcing him to eventually move to Serie A outfit Cagliari in the summer of 2013. He failed to settle in Italy, though, and just a few months later returned to his homeland to take a role at Betis.

Adan has been reborn since moving back to Spain, helping his club to promotion last season and becoming one of the breakout stars of this campaign. He is currently the goalie with the most saves in La Liga.

AS claims this form has seen him attract the attention of a number of Premier League clubs, including Liverpool, Sunderland and Southampton.

Betis officials, according to the Spanish publication, are aware of the interest from English sides, and believe that it will be hard to keep him next season as his €8m release clause would represent an insignificant sum for Premier league teams.

Meanwhile, many pundits in Spain are urging national coach Vicente del Bosque to call the player up for Euro 2016, where he would likely be third choice behind Casillas and Manchester United's David de Gea.
