Exactly, after Mbappe left I knew that it was time for Dembele to carry the club along because the clubs responsibilities will be much on him. He is indeed a good player who has been improving his performance overtime.
More work needs to be done in PSG and make them focus more on how the can win UCL because the gat the players but they lack the confidence when playing with big teams.
During this break, the PSG team must use their time to improve the mental quality of their players so that when they return to the Champions League competition they can play much better than before. And if PSG is able to win the Champions League this season, it seems that Mbappe will feel a little regretful for leaving PSG at the end of last season to join Real Madrid. Because PSG must be able to break their eggs by winning the Champions League because that is something they have never felt so far in their football careers.
Dembele is at a level where he can play at a high level for his team and most importantly, he can handle this responsibility. Dembele's contribution to the team this season is at a very good level and this contribution increases with each match. Some players can show their performance better when they find the space they want in the team. Dembele also started to perform better when his role in the team changed. Mbappe's departure allowed PSG to reach a better level in terms of performance. It would be wrong to say that the problem in previous seasons was only about Mbappe because the team was conceding very easy goals in some matches and the performance expected from Mbappe was always increasing.
PSG is one of the biggest candidates for the Champions League because the game they play is at a level sufficient for the Champions League final.
