I honestly don't see why neymar is still at PSG, besides he doesn't play almost anything all season, he doesn't score many goals at PSG, he has a good performance in the Brazilian team. i think neymar would be in teams like barcelona (ex his team) or real madrid or chelsea or city due to the style of play that is similar to his style of play. Just look at what's happening to messi on PSG, Is how if messi isn't even on the field when he play
In PSG, Neymar is less important than Mbappe. When he joined PSG, he is a biggest star there but Mbappe grows too fast and after the World Cup 2018, Mbappe is the biggest star at PSG, not Neymar. That is one of reasons Neymar wanted to leave PSG and reunite with Messi in Barcelona.
Because Barcelona can not bring Neymar back, he wanted to reunite with Messi in PSG. Fortunately, it happened but Neymar is unprofessional, and after the Coppa America, his body has too much fat and that limits his contribution for PSG.
In Brazil, Neymar is a biggest star last 10 years, after the era of Ronaldinho, Adriano and Kaka. Anyway, he is not too young and after the World Cup 2014 in Brazil, Neymar did not have too much impressive performance in big tournaments for Brazil.
Leandro Paredes, Sergio Ramos and Mauro Icardi will be missing too for this match. It seems Leandro Paredes is encountering a quadriceps issue, Sergio Ramos is recovering from a calf problem and Mauro Icardi is dealing with serious problems with his wife Wanda Nara.
Ramos does not have any match for PSG but he can help them after he recovers from injury. Paredes and Icardi don't have good positions in the club and their absence won't affect PSG too much.
