Having the status as a giant of Ligue 1, but in the Champions League they can't do much by often showing unsatisfactory performances and results. Indeed, in the Champions League their level in my opinion is still below the giants from other leagues so that's what makes it very difficult for them to do their best. Now they have to fight hard to be able to qualify at least through the play-off round. They are in the right position at the last rank of the standings that can be in the play-off round. However, their position is also not comfortable because there is almost no distance with the teams below them.
It is undeniable that in League 1 PSG is the strongest club among other clubs, but in the Champions League PSG is like an ordinary club, they always have difficulty competing. Especially this season PSG looks very difficulty in winning every match he plays, even Real Madrid who is the king of the Champions League this season, also has difficulty qualifying for the last 16 comfortably, I think many elite clubs will fight in the knockout round to advance to the last 16 such as Juventus, Man City, AC Milan, Atletico Madrid and Arsenal, they are also currently ranked quite far from the top 8.
