The goalkeeper has been tipped to leave the club this summer as they prepare to move for Manchester United No.1 David De Gea
Iker Casillas' father believes his son should stay at Real Madrid until he retires, despite the club's interest in Manchester United's David De Gea.
The 34-year-old has has spent his entire career at the Bernabeu but his future is under threat after another campaign blighted by a series of high-profile mistakes.
As a result, Madrid are pursuing a move for De Gea, which would mean the club captain would likely be relegated to second choice between the posts, but his father has urged him to stay.
He told El Pais: "He should not leave. Hopefully he can finish his career at the club that he joined 25 years ago."
Casillas also faces competition from Keylor Navas, who joined Madrid from Levante last summer but only made 12 appearances in all competitions in 2014/15.
