Real Madrid's performance will not decline next season either; they will gain more strength because of the presence of Mbappe, although even before Mbappe came in, they were doing very well. Furthermore, I think the Champions League will be very tough this season. Arsenal, Manchester City, and other teams will want to take down Real Madrid, which won’t be a difficult thing for them. But it will be too early to predict how teams will perform next season, so let’s watch and see.
Mbappe joining Real Madrid brought a lot of joy to the team because they know he’ll only add more strength to the team and eventually make the team better than before. Manchester City and Arsenal cannot only stop Real Madrid, other clubs will also want to. It is very obvious now that with Real Madrid still playing in the champions league, no team stand a chance to win it. The best way is to eliminate them from the competition which is very hard to happen because they’re always dominating the competition and always prevail against all hurdles.
Putting Arsenal as one of the reasons the champions league will be tough this season is not totally out of place but then I see some relativity around it because I still believe that Arsenal will be able to make an attempt to go beyond the knock out stage but then champions league has not been something they have really be able to handle well enough in the past years they have been playing in the champions league, at this point it even looks like the premier league is of priority to Arsenal but Manchester city and Madrid are going to be big teams in the champions league most definitely.
Arsenal is not a team anyone will see and believe that they can stop Real Madrid from winning the competition. Maybe if they meet in a more intense round they will try to win. In football, not everyone can be looked down on, so I won’t say Arsenal can’t do it if they try. The priority of Arsenal might be the premier league but I think they’ll also try their best in the champions league since they’re already there and won’t want to be exited from the competition with disgrace. As it stands, the best teams still remain Manchester City and Real Madrid as you said, we expect a more tougher competition, so I hope more teams will show more improvement when the competition begins.
