Iker Casillas has suffered a heart attack while training with Porto.
The 37-year-old goalkeeper, who won the World Cup with Spain in 2010, was reportedly taken to hospital but now is in a stable condition.
Casillas had been working at Olival, Porto’s training facility, in preparation for their league encounter with Aves this weekend.
Casillas has suffered a myocardial infarction – colloquially known as a heart attack – but was treated quickly and is not in immediate danger.
He remains in hospital and is not expected to feature again for Porto in the remainder of their Primeira Liga season.
Spanish tennis player Rafael Nadal also sent his best to his compatriot, tweeting:
“A huge hug to Iker Casillas right now. Iker Force!”
Manchester United youngster Diogo Dalot played alongside Casillas at Porto last season. On Twitter he wrote:
“Stay strong. Will be all right,” alongside the praying hands emoji.
