LOL, Does winning the UCL title or not have anything to do with their contract at PSG? Believe me, even if they don't win the UCL title, they will still play together at PSG. Then you talk about the potential for Mbappe to leave PSG, is that possible? I think that at the moment there are no other clubs that can sign Mbappe (perhaps financially) other than Real Madrid and also Manchester City, and as we know that Mbappe had already rejected Real Madrid at that time and preferred to stay at PSG because of additional offers. Manchester City, they already have a bomber from Norway "Erling Haaland".
For Mbappe and Messi there may be a little consideration, but it seems not for Neymar because we know that Neymar's condition with PSG is actually not very good from last season and there could be several possibilities regarding his future later, especially if you look at last season there were several clubs who wanted to bring Neymar even though he was hindered by a salary.
If it is related to the Champions League regarding PSG, indeed any results can still occur, but if it is related to PSG's position in League 1 then of course no one will be able to doubt PSG. Also, if we consider the results of their national team in this World Cup, it is clear that France has better results than Germany.
Meanwhile, most of the German national team players themselves come from Bayern Munich and so, if we consider this result, we can also say that PSG has a good chance to win later.
But unfortunately, we are fixated on PSG's results in the group stage which only finished runners up under Benfica. These results at least make us doubt PSG a little for the match against Bayern Munich later, it's different if, for example, PSG gets a perfect result in the group stage then of course I'm sure PSG will also get better support.
This is a very interesting match because both are teams that dominate their respective leagues, moreover PSG has many star players that PSG should indeed be able to beat Bayern Munich.
I understand his position, there is no doubt that what PSG helps him the most are his stars, is that playing against Messi, Neymar and Mbappé is quite a challenge, I know that now the Almena team is in suspense that he could be left out of the World Cup, but there is something that this team has shown, in the World Cup the Germans grow when they are in danger, and Bayern for nothing in the world will want what happened to them last season in the UCL to happen, I think they have that very clear, they will come out with everything, and they will fight until they can't, I know it will be a very spicy match, with certain airs of pique between the two, also the Germans play very well under pressure.
I really don't know at this moment which team will win, France without a doubt the level that they have shown in the World Cup is impeccable, Germany is debatable, but I think that this is something that can be easily fixed to see who can go further in the world cup however, I know that Bayern is Bayern and emotionally, and with respect to his tactics he is very good.
