"I am blushing at having to receive so much praise," Casillas told those in attendance at a LaLiga function. "It implies a lot of responsibility to have your name linked to such an important brand.
"I want to thank [Javier] Tebas, for helping make this link. I have an added responsibility in representing so many people.
"I was lucky to compete in LaLiga Santander, and unfortunately I am not there at the moment.
"What I did with Madrid will be difficult to relive, and to repeat those successes would be very complicated.
"I would love to return to LaLiga. My Real Madrid and Spain careers are in the past."
