The 28-year-old’s release clause is set at €20million, but Real and Espanyol currently hold an equal share of the stopper’s rights. Real failed with an earlier offer of €4million but Espanyol are in heavy debt and are expected to accept €6million (£4.2million) for Casilla, according to AS.
The move is expected to go through before Espanyol leave for their pre-season training camp in Austria on Tuesday.
Casilla would become Rafael Benitez’s fourth signing and will bolster Real’s goalkeeping ranks following the exit of club legend Iker Casillas to Porto last week.
The recruitment of Casilla is unlikely to alter Real’s pursuit of David de Gea.
Manchester United remain steadfast in their insistence that the Spaniard will not be allowed to leave this summer for anything less than a record fee for a goalkeeper, with De Gea having travelled with the squad on their pre-season tour of the USA. Louis van Gaal’s interest in Sergio Ramos, and Real’s similar reluctance to sell, adds another layer of intrigue to the goalkeeper’s situation.
With Real and United both refusing to budge, senior sources at Old Trafford feel De Gea may start the season in Van Gaal’s goal, while reports have suggested the keeper may wait until next summer to join Real as a free agent.
The United coach became irritated on Wednesday when asked about how De Gea had responded to being named in 26-man travelling party for the four-game tour.
“His attitude is fantastic and I have said that already,” Van Gaal said.
“It is stupid to keep asking about his attitude.”
