I think there are few different possible batterings that could result in a lot of goals. PSG already beat Anderlecht 0:4 away, so they might do an even better job at home especially with a well-rested Neymar due to his suspension on the weekend and hopefully willing to make amends.

Barcelona seem to be in fine form, but visiting Olympiacos is not that welcoming. I still think they will score a few goals and with the posibility of the Greek hosts adding a few of their own, this game is my second choice.

Additionally, Bayern are always a favorite to pump an opponent full of goals and Celtic have already been battered at home this season, so that might be happening again. They might also manage to score again against the Germans which could contribute to a higher goal tally.

There is also chances that Manchester United might have a good day and score a lot of goals, Chealsea and Roma might offer another thriller full of goals and Atletico Madrid might decide to turn it up against the minnows from Qarabag at home.
