I adefinitely agree with you because alot of teams have studied PSG pattern of play and will easily break them down just like the way that Chelsea did in the just concluded club world cup Luis Enrique should bring a new strategy and complement with this present pattern of play because clus has seen that if you can breakdown PSG midfield you have have made them powerless
Only one club has been able to beat PSG therefore we can't say clubs have been able to figure out the playing pattern or PSG. It could just be that the team was having a bad the day they played Chelsea and they're still the PSG that have been destroying everything club that they came across. We'll have to wait until the season starts before we can start making judgement on whether the team is still good or they're dead but I think they're still a good side.
