Maybe this time nothing will be different. Injuries to several players have indeed caused Man City to experience a slight decline, but this is definitely only temporary and when the players recover, Man City will return to their best performance. But if injuries attack other core players again, perhaps Man City won't get many trophies this season.
Manchester City is currently experiencing difficulty in winning games, having absolutely everything to bother about this season. Perhaps it's just a temporary condition, which means they will definitely bounce back to winning ways. I'm still surprised to see Manchester City to crumbled this season, I thought they're untouchable but with the current situation on ground, they're just as any other ordinary club in EPL. Injuries affects all clubs in EPL and Manchester City have started suffering from it. Pep Guardiola have missed points on important games this season, they're currently sitting third position on the table.
Manchester city cannot be tagged as crumbling yet, they have lost only two game this season and the losses were just immediately after they began to suffer some Injuries, something that is common amongst all team, whether big or small there are times injuries could affect any team so bad it will reflect in their performance aswell and i think it's same thing Manchester city is suffering at the moment.
They could be said to be at a slow phase for the moment but they will definitely get back as gardioula is known for his strong will to always get the job done regardless of the circumstances, I'm sure he will come up with a tactics good enough to be able to deliver and get the team back to the top spot on the table. by January transfer windows he will be getting good substitute/replacements for injury prone players and then he will be good, he is known to be very good with choice of players, so what ever player he decides to get by January I think will be best substitute/replacement for those he probably want replaced.
