Sergio Aguero has admitted he could miss eight matches with the latest in a series of hamstring injuries.

The Manchester City star tore his left hamstring while chasing a long ball downfield during Argentina’s 2-0 defeat to Ecuador last Thursday night.

Initial estimations were that Aguero could miss a month but Football Insider revealed last Saturday that Aguero could be sidelined for up to six weeks with what is a Grade Two hamstring injury.

The striker has admitted that he might not be available to return until the Premier League visit of Liverpool on 21 November.

He said: “I hope I can be there against Brazil [on 13 November] but the injury must be let to recover a bit so there is no relapse. This is an injury you have to recover bit by bit but of course I want to be back quickly.”

Aguero’s absence a shattering blow for Manuel Pellegrini, who could be without the 27-year-old for eight fixtures, including the Manchester derby, home-and-away Champions League clashes against Seville and the home match against Liverpool on 21 November.

Aguero scored five goals in City’s 6-1 annihilation of Newcastle 10 days ago before being substituted at the 66-minute mark. In total, he has netted eight times in 11 matches for the club this season.

City will be cautious with the centre-forward’s recovery given his troubled recent past with injuries.

The striker was reported to have been in tears in the dressing room after the game and was immediately released from international duty.
