Porto president Jorge Nuno Pinto da Costa doesn't expect Iker Casillas to return next season.

The Real Madrid legend is recovering from a heart attack suffered at Porto training a fortnight ago.

The ex-Real Madrid player signed for Porto in 2015, and has played 156 games with The Dragons, keeping a clean sheet on an impressive 74 occasions.

"We have a problem with Casillas, whose contract we had renewed and we didn't need to sign any goalkeeper.

"Now we think we're going to need someone, but that case is also being treated," Pinto da Costa told O Jogo.
