Real Madrid legend Iker Casillas admits he wants to make the most of his final playing days with Porto.

Casillas says a retirement date, however, has not been set.

He told Expresso: “You're thinking about what can happen within the next few years. It's the nature of life. I don't have 10 years of football left; I don't think I can play until I'm 47.

"When I was 17, I thought I was going to play until I was 27, and then until I was 32. I'm closer to retirement than playing on, so I have to enjoy the time while I'm still here."
