The Spanish shot stopper has 18-months remaining on his current deal, so it may make financial sense to sell now, rather than risk losing him for a reduced fee in the future.

David de Gea is reported to be worth a sizeable £50m
Reports suggest United chiefs approve of Falcao's permanent residence at Old Trafford, and will launch a significant bid during the summer.
Falcao is contracted to the French club until the summer of 2018, meaning United have little leverage with which to negotiate a cut-price deal.
The 28-year-old hasn't exactly set the Premier League on fire, but has shown enough tenacity and boasts an immaculate goalscoring record to suggest £43million is a fair fee.
According to Francois Gallardo, described as a FIFA agent, Vanja Modric is unhappy in Madrid and could play a major role in her husband's return to the Premier League.
Gallardo said: "Modric is the engine of Real Madrid, but the problem it is his wife who did not fit into Madrid in Spain."
United are known to be in search of a midfield dynamo capable of linking-up play and protecting the back four.
Numerous efforts to land Kevin Strootman and Arturo Vidal have failed to yield any results, and could see Van Gaal submit an offer for the former Tottenham man.
