Porto goalkeeper Iker Casillas is thought to have retired from football after suffering a heart attack in early May.
The former Real Madrid shot stopper was rushed to hospital during a training session, and was confirmed to have suffered a heart attack. Fortunately, he recovered and was discharged from hospital just a few days later.
However, according to The Sun, the health scare has left Casillas considering his future, and he has ultimately decided to retire at the age of 37.
Widely regarded as one of the finest goalkeepers in history, Casillas made his name with Real, rising up through the youth ranks before making his first-team debut in September 1999 at the age of just 18.
