Man City this season is a little different. Because Gundogan had left and joined Barcelona at the start of the season. But De Bruyne's figure seems to be quite reliable there. After De Bruyne recovered and returned, we could see that the attack built by Man City became more well organized, just like when Gundogan was present.
Real Madrid does have a good attacking midfielder like Bellingham who is even able to score lots of goals like a striker. And the young players at Real Madrid can also be relied on. So Real Madrid will actually continue to experience improvement from season to season. But I can't predict which team will score more goals. But if Real Madrid fails to keep Haaland tight, then Man City could score first.
In this season, we have completely different level of quality from the many teams which is surely not surprising because this is part of the game specially while teams are having transition period which is usually happened regularly currently we have all teams in different level performance and things can go either way we can't give favourite tag to any team even we all know Manchester City is currently at his best because Real Madrid is also impressive and things can go into their favour as well De Bruyne is big player, but Jude Bellingham is also having impressive season which can give them good success into this season with many top players are also giving him good back up which is best of the Carlos Ancelotti upsets are surprising performance is also part of the Champions League.
