Manchester City boss Manuel Pellegrini has voiced his concerns over Vincent Kompany's ability to return to full fitness as the defender continues to struggle with injury.
Kompany remains sidelined after suffering a thigh injury against Everton five weeks ago, shortly after he returned from a groin problem sustained in the opening round.

The 27-year-old has only played four league games this season and Pellegrini is hopeful he will return to action against Tottenham on November 24, as he expressed doubts over Kompany's lack of football recently.
"Of course we are concerned about that and we are trying to do all the best to see how we can improve in that sense," Pellegrini said. "He has two weeks more. We hope if he continues the same way he will not have any problems."
When asked about reports that Belgium have sent their own physiotherapist to aid the national team captain's recovery, Pellegrini added: "I don't know about that."
David Silva has joined Kompany on the list of City casualties after injuring his calf in the Champions League win over CSKA Moscow on Tuesday and the Spain international could be out for up to a month.
"He has a problem with his calf," Pellegrini said. "I don't exactly know how many weeks it will be but maybe three or four. I don't think it is only Silva. We have an important squad here, and now in the international break next week we will have just four players. All the other players play exactly the same, not only David Silva."
