The Blancos skipper feels he and his team-mates will be able to play with greater freedom now that they have realised their 10-year wait for a 10th European title
As club president Florentino Perez admitted last season, winning a 10th European Cup had become an "obsession" for Los Blancos, so May's Champions League triumph sparked wild celebrations among the Santiago Bernabeu faithful.
Casillas, though, has intimated that he and his team-mates were as relieved as they were ecstatic after their 4-1 victory over city rivals Atletico in the final and suggested that they will now be able to play with greater freedom having finally ended Madrid's 10-year wait for 'La Decima'.
“Winning the 10th title was the cherry on top of a great season," Casillas is quoted as saying by Abola.
"It allows us to lift the pressure of not being champions of Europe since 2002. Now, free of anxiety, a lot more can come.
"The shirt of the biggest club in the history of football comes with responsibility: each season you have to give the maximum and give happiness to the fans."
Despite looking set to leave the club this summer due to the arrival of Costa Rica's World Cup hero Keylor Navas from Levante, Casillas now seems set to stay at the Santiago Bernabeu.
