Sevilla are considering a move for Liverpool star to fill the gap left by the departure of Ever Banega to Inter Milan, according to Estadio Deportivo. The Europa League winners are concerned, however, that the Wales international's performances at Euro 2016 could spark a big-money auction for his services, with Swansea City and Celtic also being linked with his signature in recent times.
The Sevilla-based publication claims Sevilla's sporting director Monchi has been following the development of the 26-year-old midfielder since his days at Swansea.
The Andalucian outfit did not make any approach to sign the player in the summer of 2012, when Liverpool paid Swansea around £15m ($22.2m). However, Monchi believes this summer is the perfect opportunity to sign the player, as he has one year left on his contract at Anfield and could be available on the cheap.
Furthermore, Allen himself revealed recently that he could leave the Premier League side should Jurgen Klopp fail to give him any assurances over his role next season.
Allen said to The Guardian: "I think it [my future] hinges on the pre-season plans and what exactly the club are hoping to do, everything comes into that. The acquisitions and who they are going to get in. Until all that happens it is difficult to answer that question. As a footballer you want to play every minute of every game. When you don't it can be disappointing. That's natural for anyone; that's not specific to me. It's how you react. You have to make sure you don't let it affect you to a point that, when you do get your chances, you're not up to it."
Estadio Deportivo claims that Monchi has put Allen on his list of candidates to replace Banega, after the Argentine opted against renewing his contract with the Europa League winners to move to Inter Milan.
Yet Sevilla may still miss out, with Allen's valuation increasing during the European Championship following a string of impressive performances for Wales. The Spaniards believe Liverpool may keep the player, or seize the opportunity to start an auction and make the most from his sale.
The Daily Telegraph has claimed Liverpool are open to offers of around £10m to part ways with the midfielder. Swansea are said to be keen on luring him back to the Liberty Stadium, while Brendan Rodgers recently suggested he would be keen on a reunion at Celtic.
