The Spanish goalkeeper sees absolutely no reason to leave the Bernabeu.
Despite the ongoing speculation surrounding his future, in comments after the gruelling win against Atletico Madrid on Wednesday night, via AS, the 33-year-old reaffirmed his commitment to Real Madrid.
Asked whether he will remain at the club, Casillas underlined: "I hope and wish to achieve the greatest number of titles I can. I hope to fulfil my contract and when you make a commitment, it has to be backed up until the end."
Despite his exceptional history with Real Madrid, Casillas remains conscious that his place in the team can always be at risk. He acknowledged: "I have to earn it, train for it, battle and fight for my place."
He also assured reflectively that even if he wasn't first choice: "I'm now of an age when I see things differently. If I'm not first choice, I still have a commitment to the younger players."
Even if Real Madrid sign another 'keeper this summer, given the links with Manchester United and Spain colleague, David De Gea, the experienced Casillas fully intends to see out his contract until June 2017, with Los Blancos.
Stressing that he's happy at Real Madrid, whether as first choice or not, Casillas turned the questions about his future around, suggesting: "Why wouldn't I stay at Real Madrid, if I'm not the starter?"
Since the arrival of Costa Rican international, Keylor Navas, who has made 9 appearances, Iker Casillas has been the firm choice for Carlo Ancelotti between the posts, having played 41 times this season in all competitions.
Compared to the previous two seasons, when he was rotated with Diego Lopez, this season Casillas has been the unquestionable first option. Whether that situation changes beyond the summer, he has no doubts about staying put at the Bernabeu.
