Manchester City's Sergio Aguero will struggle to be fit for World Cup, says Argentina FA doctor

Manchester City's Sergio Aguero will struggle to be fit for the World Cup, according to Argentina Football Association doctor Homero D'Agostino.

The striker underwent keyhole surgery on a knee problem which has troubled him for a number of week, having not started a game since City beat Chelsea on March 4.

He returned off the bench for the derby loss to Manchester United but a controversial challenge by Ashley Young left him unable to fully train.

D'Agostino predicts a five-week recovery with the World Cup under two months away and expects Aguero to be in a race to regain match fitness ahead of facing Iceland on June 16.

"That a player has undergone an arthroscopy with 60 days to go before the World Cup is worrying," D'Agostino told Radio 10.

"The recovery process will require at least five weeks. When one has old injuries, the recovery process is not as fast as one would like it to be. It's never going to be less than three or four weeks, or even more.

"I imagine that he will not arrive 100 per cent fit with the limited time that is left before the World Cup. The anatomy is the anatomy. The injury is what it is. He can try but I don't think he will arrive 100 per cent.

"The important thing is to know what he had. The doctors would have tried to resolve the issue in a conservative manner, non-surgically, but they were unsuccessful. The arthroscopy is a process that you do when there are old injuries."
