The Spanish goalkeeper, who has been forced to play second fiddle to Diego Lopez in the league this season, has admitted that he has 'been waiting 11 years' to pick up another European crown.
"We're working for it. We're training for it but we can't go crazy because even though right now people are praising us, that can take the edge off. We need to keep going as we are right now and wait for the end of the season," said Casillas at an anti-bullying event on Tuesday.
"This is a young, ambitious team. Hopefully, we'll win the Champions League - we've been waiting for it for 11 years - another league and, why not, the Copa del Rey."
Casillas has been linked with a move away from Madrid at the end of the season.
