PSG had many star players in their squad, but their coach was not good. There was no friendly relationship between the players in the squad. PSG team cannot do well in Champions League due to lack of friendly relationship between players and lack of understanding between players. But now PSG has an experienced coach like Luis Enrique. Now, if PSG's squad was as strong in attack as before, PSG would have been able to dominate the Champions League.
You are applying some weird logic to be honest. Since PSG never won the Champions League although they had Mbappe, no team that has Mbappe will ever win the Champions League. That is how you construct your arguments. Think about it.
I mean a star player who can consistently perform consistently, and has the ability to score at key moments and bring the team to victory. There are very few such players. But PSG was very lucky to have three of the best players in the world in Messi, Neymar and Mbappe in their squad. But they cannot use these three players properly. This is why the PSG team does not get a chance to touch the Champions League title.
You probably didn't read my comment properly or you didn't understand that. I don't blame Mbappe at all for PSG not winning the Champions League despite having Mbappe. The bonding between PSG's players was not good and that's why they couldn't dominate the Champions League, that's what I mean. If the understanding between the players is not good, even if you bring all the best players in the world in the same squad, the expected results will not be obtained from them. This is what I believe.
