Sergio Aguero: Manchester City striker out for up to eight weeks

Manchester City striker Sergio Aguero could be out of action for up to eight weeks, says manager Manuel Pellegrini.

The Argentine, City's leading scorer this season with 19 goals, injured his calf during Saturday's 6-3 victory over Premier League leaders Arsenal.

It was thought he would be out for a month but Pellegrini revealed the latest prognosis after the 3-1 Capital One Cup win over Leicester.

"The doctor has said he has at least one month or eight weeks," he said.

Aguero, who has scored 13 times in the league, netted the opener against the Gunners before limping off at the start of the second half.

"I don't know how many weeks but it will be at least one month," added Pellegrini. "It is very difficult to know at this moment."

If Aguero is sidelined for eight weeks, he will miss crucial Premier League matches against Spurs and Chelsea.

He could also sit out the first leg of City's Champions League tie against Barcelona on 18 February.

City are also waiting for news of defender Pablo Zabaleta, who limped off after just 12 minutes at the King Power Stadium with a hamstring injury.

Fellow defender Micah Richards suffered the same problem during the 3-2 win over Bayern Munich last week.

"It's a pity for Pablo because he felt a little problem in his hamstring and we'll see tomorrow how damaging it is," said Pellegrini.
