Actually, the new arrivals also spiced up their game at some point, remember they didn’t have that much of a good game at the group stage but that changed completely after the group stage and the first team that tasted their wrath was Brest (with 7-0 defeat)..
What if Mbappe was ther?  I still think they were going to win anyways with or without mbappe and besides even at RMD Mbappe wasn’t the flop but yeah he flopped earlier at the beginning of the season
