I don't even see it as a surprise performance. How can the horrible performance from PSG can be called as a surprise performance? PSG is even declining compared with last season. I don't wanna underestimate PSG but im talking about the reality if PSG was always too inconsistent in any game.
There have been also many rumors about dembele was not feeling confidence anymore in the club. He may leave from PSG soon along with mbappe caused by they are willing to join in new clubs.
Im willing to see those guys will able to get better clubs than PSG even though that if dembele was a new player in PSG right now. It's time for mbappe to get a new achievement for that.
PSG's performance in the loss to Newcastle wasn't bad, but they just failed to capitalize on opportunities to score. Moreover, Newcastle had a good defense when PSG built attacks, so even though PSG had several opportunities, the defense was still able to handle them. Of course that has benefited Newcastle, but that doesn't mean PSG doesn't have a chance.
PSG and Newcastle adopted different strategies throughout the match. PSG played very offensively and Newcastle played very defensively, this benefited Newcastle in preventing PSG from scoring goals and they also benefited because PSG did not concentrate on defending. But I'm sure PSG won't make the same mistakes when they play at home for their second meeting with Newcastle, so I don't think the defeat will punish them for the rest of the season.
