Real Madrid legend Iker Casillas is set to have his future at Porto settled this weekend.

Porto goalkeeper Casillas, if he faces Tondela, will reach a set number of games to trigger a 12 month option - which he can accept on his side.

"My intention is to stay a year. I think it is also the intention of the club," he said.

"I can decide if I stay or not.

"The president agreed with me that I only have to say so a month and a half before the contract ends."
