GOALKEEPER Iker Casillas has been told he must undergo medical test to determine if he can play again following a heart attack.
The 38-year-old Spain international had a heart attack in May which had looked to be career-ending.
The former Real Madrid player was training at his new club Porto when he fell ill.
Doctors later determined the goalie had suffered an ‘acute’ heart attack and will now further undergo test before the end of the year.
Casillas has dismissed speculation that he will be hanging up his boots for good, despite being advised to retire.
The Word Cup winner said: “The day will come when I have to retire.
“Please allow me to announce that decision when the moment arrives.”
Porto manager Sergio Conceiçao has also spoken about Casillas’ work ethic and ambition and expressed hopes that he will return.
