City are going through a bit of a bumpy patch, and the last thing they need is a big influence like Kompany missing more games.
Kompany picked up the injury in the 2-1 defeat to CSKA Moscow in the Champions League prior to the international break and missed the subsequent trip to Loftus Road where the Premier League champions were held to a 2-2 draw by Queens Park Rangers.
During that game, Martin Demichelis partner Eliquim Mangala at the heart of the defence and the pair looked far from convincing against Harry Redknapp's relegation threatened side.
Aside from the fact the City captain is a top class centre-half, when the side is going through a bumpy spell during the season, the last thing they need is arguably their best player on the sidelines. They need a reassuring voice at the back as they know they have the quality to hurt any side going forward given the wealth of attacking talent at their disposal.
Demichelis is an experienced defender and Manuel Pellegrini probably feels fine with the Argentine at the heart of the defence but the uncertain start to life that Mangala has made to life at the Etihad Stadium means that opposing teams will feel there is a weakness to be exploited, and all the more so when the team's leader isn't alongside him to guide him through the game.
There is a chance that Kompany could miss the visit of Swansea City, and even now City will feel they can ill-afford to drop more points this season if they are to keep pace with Chelsea as Kompany looks to be the man who will lift a third Premier League crown in four years.
Swansea are full of confidence with an in-form striker in Wilfried Bony that are on a high after their win over Arsenal, which has been typical of their good start to the season which sees them not far off the Champions League places.
Then comes the crucial game with Bayern Munich, with all the attacking talent we have, even if they decide to rest a few players given they are already guaranteed top spot, they have the firepower to exploit any weaknesses in the defence.
Without Kompany starting, it would be a big blow, so City will have their fingers crossed he will be available shortly after the break.
