I don’t think that the likelihood of such a final is high - firstly, the teams can meet at earlier stages of the tournament, and secondly, they are not favorites. Take a look at the bookmakers' odds on who will reach the final:
Manchester City 1.96
Fc Bayern Munich 2.58
Real Madrid 3.19
Arsenal 3.68
Now the quotes are a little distorted because City have the easiest opponent of all possible and we can say that City are already in the quarter finals, but in any case they are the favorites of the tournament and in order for us to see the final without them, someone has to knock them out. I would like to believe that someone will succeed.
Why's Arsenal on this list? They're not the side to leave there,I'd rather want to see Paris Saint Germans.
Real Madrid with that odd because they have no good enough striker. They're still my favorites to win regardless.
Bayern Munich are good I just double doubt the impact Thomas Tuchel can bring Into Bayern Munich and the players, Manchester City yet again Buzzing with the return of Kevin De Bruyne back. He's already made a great impact right now in this game. They have a very good chance of defending but I won't support until they do win.
Arsenal are in the top group of the Premier League and they are consistently good. Who are PSG? At the moment, this can be said to be a new team and even if there is a top player Mbappe, but this team always suffers from low competition in Ligue 1. There are rumors that PSG will loan Benzema until the end of the season, but Benzema is a striker and with this PSG has no problems, so he is unlikely to seriously strengthen the team. In general, Arsenal are naturally higher than PSG - they are better in all respects.
