Fresh news are about Naymar who will not play in coming games because of injury
PSG announced today he'll be out for 10 weeks. He won't get surgery to his foot.
That's a bad news for them, and Manchester United will fancy their chances of qualifying, PSG still do have players than can cause Man Utd big problems if they are fit for the fixtures.
It might increase their chances but not as much as you think, I don't think they can catch up with the two goals PSG have in their first match. The next game will be held at PSG's home so the advantage is on them playing on their match. Neymar didn't even play on their first match so I don't it would make any difference at all, right now Mbappe is their main man and as long as he is on the team they can still repeat what they have done on the first match.
