Real Madrid legend Iker Casillas will be remembered as one of the outstanding goalkeepers of his generation, but the veteran was left red-faced after a high-profile error while playing for Porto on Saturday.
Trailing 2-1 against great rivals Sporting CP with just a handful of minutes left, the World Cup winner contrived to let an effort from Bruno Cesar squirm past him.
Even a despairing slide tackle from Casillas was not enough to prevent the ball crossing the line and spare his blushes.
Porto lie third in the Portuguese top flight with no chance of catching top pair Benfica and Sporting, who are first and second respectively, and the goalkeeper's slip added insult to injury in a frustrating loss.
