Aguero is suffering from a second hamstring injury of 2014 after limping off at half time in City’s defeat at Barcelona in the Champions League earlier this month.
It was originally thought that the Argentinean would only miss one or two games but the 25 year old is still not back in training ahead of today’s clash with struggling Fulham.
Pellegrini has confirmed that his main man will definitely miss Tuesday night’s derby with Manchester United and is a real worry for clashes with Arsenal, Liverpool and Southampton coming up.
“We don’t know yet, but maybe next week he will start working with the squad.
“I don’t think the whole week, maybe at the end of the week he can be with the squad starting training.”
“For United, no, no chance.”
Aguero has been in fine form when fit this season but you can count the number of games he has played in 2014 on one hand.
