PSG had three superstar players on the team and they tried their best to have a better performance in the Champions League but still, they couldn't do that and even the players they had like Messi left the team. I think now after Mbappe leaves, they will have bigger problems but as Enrique said, they will try to fill the place of Mbappe in the team by using all the players they have by having better teamwork.
It is a tough job and maybe Luis Enrique is aware of this and he will try to do his best for the next season. But the support of the players he needs must also be fulfilled by the management because relying on the existing players will be difficult. Building a stronger squad is not easy and it is proven that adjustments have to be made from season to season. Now a big step has to be taken and losing Mbappe will be a threat in the front line when they play in the Champions League next season if they don’t have a replacement.
Like the previous seasons with the three big names Lionel Messi, Neymar and Mbappe, but PSG also struggled to achieve success in the Champions League. Teamwork, players supporting each other and the coach are very important, maybe this kind of work is what PSG must improve on next season.
