The Argentine midfielder could be available on a free transfer next summer but they face competition from Juventus and Roma.
The Argentine midfielder is out of contract next summer, and at this moment in time it seems unlikely that he will sign a new deal with the Andalusians to stay in La Liga beyond that point.
The talented midfielder is one of the biggest names among those available on a free next summer, and that has sparked interest across Europe in securing him.
Chief among them are Premier League duo Everton and Manchester United, who would be keen on moving for the player.
However, they would face competition from Italy in particular, with giants Juventus and Roma also interested in securing him on a free transfer, according to TuttoMercatoWeb.
And that could happen sooner rather than later, with him able to discuss pre-contract deals with any club from 1 February.
However, the La Liga side are naturally keen on retaining one of their star players, who was a big part of their success last season, and they are actively working towards him signing a new deal.
