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.
When City played their match in the Group G phase, they got maximum points even though several players had to be absent due to injury. one of them, Kevin De Brunye, had to be in the treatment room for quite a long time. nevertheless, Pep Guardiola's squad did not experience any significant problems when playing their matches against teams in the Group G phase. now, De Brunye has returned and recovered from his injury. even though Pep didn't play him as the main starter in the match against Newcastle, De Bruyne was able to maximize his ability and stability even though he only played a short 21 minutes. Gradually, Pep will return De Bruyne as the main player in his starting eleven. at least, City now has additional ammunition options that can be relied upon in every City match. especially, in the Champions League competition which seems to remain Pep Guardiola's target to defend the title they won last season.
In the round of 16, City will play the away match in the first leg at home to Copenhagen. in theory, City will not experience any significant problems in the next match. which means, City's probability of qualifying for the next round is quite high. Likewise with Haaland, this player from Norway is predicted to make a comeback at the end of January. If it is true according to the predicted schedule, Haaland can be played when City plays Copenhagen later. both in the first leg and in the second leg. so, this way Pep can play his two mainstay players like last season. the combination of Haaland and De Buyne will be a problem for the teams that will be their opponents later. Let's see how De Brunye plays his matches, especially in the Champions League. likewise with Haaland, who is scheduled to return at the end of this season. thus, Pep again has a squad he can rely on. but to be sure, let's see and wait to see how it develops.
