The problems in the relationship between Mbappe and Neymar have been talked about a lot more recently than the problem in the relationship between Mbappe and Messi.
The owners of PSG definitely made a big mistake when they decided on the strategy of buying the biggest stars of world football, not realizing that each of these footballers has a big ego and wants to be the biggest and most important in the team.
Of course, this is not possible in reality, and due to the conflict between the main stars of the team, the whole team has been playing badly in the French league lately, and they are no longer favorites in the Champions League either.
The owners of PSG really invested huge money in the team but now they understand the hard truth that success in the Champions League cannot be bought with money and that although they have the best players in the world, they do not have the best team in the world.
I have a slightly different view.
I think Messi is well aware that he cannot perform extraordinary at his current age. in the first season, Messi had a little difficulty adapting. in the second season, messi played more as a playmaker to serve his two colleagues, namely Neymar and Mbappe. meaning, Messi has left his ego to no longer always score goals. the problem that happened was with Mbappe, he felt he was more special than the other stars. The feud between Mbappe and Neymar is very familiar to us, even rumors regarding PSG stars never escape the news. in fact, not infrequently they still play professionally on the field.
The problem is, PSG do not have midfielders who are creative enough when building attacks. especially when facing teams that tend to defend. I think last January, Galtier will bring in a newcomer who plays as an attacking midfielder. but in fact, that didn't happen. related to Mbappe's injury, by the way. as we know, PSG's front line will be slightly less sharp. but in truth, we cannot rule out the existence of Neymar and Messi. because after all, Bayern will not underestimate PSG in the first leg later.
