The truth is, they have to work harder to win the champions league. On the face of it, Mbappe is forced to assume the offensive power alone. In this case, it is bad for PSG that the offensive zone, which weakened without Messi and Neymar, is left alone in Mbappe. They have Dembele next to Mbappe, but they also need a finishing striker like Haaland in the future.
I'm not too sure if PSG this season are targeting the Champions League trophy, but rather rebuilding their squad under the tutelage of Luis Enrique. In fact, there is not much PSG or Luis Enrique can do to bring in the players they are targeting this summer. moreover, Financial Fair Play is shining a spotlight on them. Previously, PSG wanted Premier League captain Harry Kane, but he was not willing to join the French league giants. Apart from that, PSG targeted Bernardo Silva, and in fact they failed to bring him to the Parc des Princess.
But at least now PSG have many options, they have Goncalo Ramos, Kolo Muani, Dembele, Assensio, and finally their star Kylian Mbappe. In midfield, there are several players who are playing well even though they are still short on midfielders. back line, Enrique has many options. this time PSG is not like last season, even though Messi and Neymar left. but they have a competitive team, both in front, midfield and defence. thus, at least they can still defend the Ligue 1 trophy. For the Champions League, Enrique must build his team to be even more competitive. at least, he still needs some players who have above average quality than at the moment. So, I assume PSG is not aiming to win the Champions League trophy. but that doesn't mean they will just miss it. We'll see how far Enrique takes PSG.
In this season, I think it will be better for PSG to concentrate on the Ligue 1 title. Because of the current problems that they have right now going on in the squad, I do not think they will be able to win the Champions League. Even in the league competition, they did not start very well. They were not able to win the first two matches.
Right now they are in the second position and they have been able to win the last two matches. But I don’t think they are actually going to be consistent. Mbappé alone, cannot bring them to the Champions League. He will only be able to have a good enough contribution to bring them the Ligue 1 title. But we all know that the Champions League competition is a lot harder competition.
