Iker Casillas says he "suffered" when frozen out at Real Madrid last season.
"I thought about the team, what is best for Real Madrid ... I cried, I suffered, I've asked what went wrong, I've had bad nights sleeping little and soul searching ... I am a Madridista, and above all, for me, before coaches, presidents, athletic directors, is the club.
"I would love to retire at Real Madrid, but I will put no impediment if tomorrow a coach does not want me."
