PSG is lucky to have too many top quality players in their squad which can help them for having better results into domestic league, and they can win this without their few top players as well but for the Champions League surely they need availability of their top players which help them for having good performance and better chances for the win in this season hopefully all will be clear in few weeks, and they will be able to perform with their best.
PSG don't have enough confidence in important matches and who is their captain? Their captain is Marcos Marquinhos and he is the heart of PSG defense. Honestly in many seasons, PSG lost their big advantages by conceding one, two or three goals very quickly. In World Cup, he made mistakes again and contributed to Brazil defeat.
Sergio Ramos has lot of experience and confidence but will he be able to force Marquinhos to play better?
Things are interesting as Bayern Munich is also missing their striker Sadio Mané even they are also having few good replacements but still this can hurt their chances for the win in this season into Champions League, but few players are also good and improving which will help there for the best results.
Bayern Munich will have bad German players with super bad mood after returning from World Cup. I really believe that Bayern will have not too good matches a few weeks after Bundesliga resumes in January.
