The bad part about what City going through right now is that KDB is back, and we all know how kevin plays, that dude has been awesome ever since his return, just a couple games and he is already doing things that saves them, dude is amazing and I agree that he is going to end up being even better. But that doesn't change the fact that we are talking about a missing player yet again.
They got Kevin De Bruyne back, but they are missing Haaland right now at the same time, those two were the best duo in all of football world last season, and they haven't played any games together this season so far I think, or if any, that must be before KDB got injured. So City is not even at 100% right now and will take a while, need to get Haaland back, and both those players in 100% shape.
But I think, the main factor that can restore Manchester City performance is De Bruyne because after all, previously Manchester City was also still able to play Haaland. But ya, the result obtained is, Haaland cannot really guarantee good results for Manchester City and thus, Manchester City position has also previously dropped to 4th place in the Premier League standings . So ya,even if for example later in the Champion League match Haaland is still unavailable due to injury but ya, I think Manchester City will still qualify for the quarterfinals . Because after all, Manchester City will also only play against Copenhagen in this round of 16 and thus, there is still plenty of time for Haaland to recover and play in the Champions League in the quarter-finals later.
Since the start of the season, Kelvin De Bruyne has been absent from the Manchester City team and that was because of the injury he picked up in the beginning of the season but that has not stopped Manchester City from performing well in the UEFA champions league competition as they finished the group stage of the competition as one of the only two clubs to have won all their games in the group stage of the competition.
Manchester City is been managed by one if the best managers of modern day football Pep Guardiola and that's why they can still win the UEFA champions league trophy even without their key players unlike many other European teams. But now that Kelvin De Bruyne is back to action, Manchester City's chances of winning the UEFA champions league competition this season has significantly increased because of how good of a player the Belgian is and how he can easily change the results of games on his own.
