In addition to what you said, this season it seems that PSG will also be more overwhelmed to compete in the Champions League because the opponent that PSG will face in the last 16 is Liverpool. This is quite a tough challenge for PSG because the team immediately meets a very tough opponent in the last 16, while in Ligue 1 itself PSG can still compete more relaxed because the points gap that PSG has is quite a lot with all its rivals.
Facing Liverpool has gat to be one every big challenge PSG will be facing in the Champions League this season and it doesn't look like it's going to be an easy one for them because this season Liverpool is on fire and are willing to make sure they have a chance at the champions league, at least getting to the finals is their target hence I'm only hoping for PSG but I'm even more optimistic about Liverpool.
