フロレンティーノ・ペレス
After much speculation about his future, on 11 July 2015 Casillas signed with Portuguese Primeira Liga side Porto on a two-year deal with the option of a one-year extension. Real Madrid's conduct in his exit was criticised, with Casillas' parents claiming that he was being forced out of the club by president Florentino Pérez, who received calls to quit from fans. Former international teammate Xavi, who earlier that summer left Barcelona after a similarly long and successful career, claimed that Real Madrid were ungrateful of Casillas' service to the club.
