Manchester City defender Aymeric Laporte could be out of action for up to a month with a hamstring injury, manager Pep Guardiola confirmed on Friday.
The Frenchman was forced off in the first half of Wednesday's Champions League victory at Real Madrid -- just his eighth appearance of an injury-ravaged season.
"He has a hamstring injury, so that is normally three weeks or one month, more or less," said Guardiola.
"We tried to avoid it but unfortunately it has happened after four or five months out and then going directly into a big game. It sometimes happens."
"If you think, 'I am an unlucky guy', you will not improve. It is what it is. Accept it and work harder to come back in the best condition as possible."
