As for the teams, they will play the first match in suboptimal lineups and suboptimal form. For one of the teams, this will be fatal - as one team will go further, and the second, which also planned the peak of form for the later stages of the Champions League, will leave the tournament.
I agree, Messi’s magic seems to have disappeared since he came to Paris
I read somewhere that Messi is not yet fully ready due to health problems, that he is unhappy in Paris, has no friends, doesn't know the language, that he uses every opportunity to visit Barcelona etc.
It seems to me that Real is a more complete team than PSG and has a better chance of winning.
PSG have too many stars in the team, Messi, Neymar and Mbappe, who think they are bigger than the team, don't like to help teams in defense etc.
Against weaker teams this is not a problem but against top teams like Manchester City or Real, it is a serious problem in the game.
Messi has been playing in the same team all his life in the same formation, so it is difficult for him to adapt. Plus the biggest reason is age. As for problems with language and lack of friends, it sounds doubtful - there are a lot of Spanish-speaking players in PSG and a lot of those whom Messi has known for a long time. I think he will have more problems with socialization if he returns to Argentina than in any European club.
I doubt age is the problem, he played great in spain despite his age. I won't compare him to Ronaldo because it's silly and hackneyed, but I agree about the adaptation. To play for one club for so many years and then move to another club and continue to play at the same level is very difficult. It`s unlikely about the language, I`m sure they all talk to each other, they just don`t have the chemistry yet. I've seen many moments when Messi was in an open position but they just did not give him a pass because they did not understand that thay had to do so.
Messi isn't in best shape right now, that's true. I mean he had a couple of health problems, including Coronavirus and his Champions League performance wasn't all that bad. Didn't he score 4 times or so so far? Let's see how he will be doing during the final stage games. Ligue 1 seems to not really be representative of his actual performance. I think he isn't really that motivated in Ligue 1.
