Last season, Man City maybe was able to beat both of them. Because last season Ral Madrid and Bayern were not in good enough condition. But this season I think something is different. Because Real Madrid and Bayern this season really look more solid than last season. Meanwhile, Man City has had many problems this season. De Bruyne has also just recovered and has returned to playing and indeed he can immediately return to his best performance. But Haaland hasn't returned yet, but I haven't heard any news about when Haaland will return. Even though there are lots of rumors circulating that Haaland might be able to return at the end of January, I'm still not sure whether he will immediately return to his best performance or not.
De Bruyne can immediately return to his best performance but we still don't know about Haaland. So this season the UCL will probably be fiercer than last season. Unless Haaland returns and remains in good form then Man City's chance of winning the UCL title again could indeed happen again.
Inter Milan is also something to be reckoned with. Because this season Inter Milan also looks stronger than last season. And Serie A clubs are sometimes difficult to predict. And can always make other strong teams overwhelmed when facing them.
By February the knock out stage for the UCL will kick off and for some teams, it'll be an easy slide through regardless of the notion of the strongest teams being the ones able to scale into this stage. City and Copenhagen would go against each other and it's very much clear that City would be the survivors.
Their key men are back and set to run and definitely that's enough charge to weigh down Copenhagen.
Yes, in their home ground, they may try to put up a battle but I'm certain that City will be capable to overturn them. They're way ahead of them in capacity and ability too. As always, the round of 16 will have as much fun as there can be in it and it's greatly anticipated. Preparations and games would definitely be intense too. That's why there's the winter window, for clubs to strengthen their squad depth ahead of competition like this, cause it going to get tougher and the wicker teams would definitely get kicked out.
