Former Spain and Real Madrid goalkeeper Iker Casillas has been hospitalised after suffering a heart attack in training, said his club.
Casillas, 37, who plays for Portuguese side FC Porto, suffered an "acute myocardial infarction" on Wednesday morning.
FC Porto, who said Casillas was "stable and his heart problem resolved", tweeted their support for the shot-stopper.
Former Real Madrid teammate and Spanish national skipper Sergio Ramos added to the response.
Welsh striker Gareth Bale, who also played with Casillas for Real Madrid, wished him well too.
