Currently Arsenal has been the only team in England that I can say for sure may give PSG some tough time if they ever get to meet, their only problem will be with their mentality, I do not trust Chelsea to stop PSG from lifting the FIFA Club World Cup this time, except PSG suffers a bad day, Chelsea is not their match currently. I hope Chelsea use this to gain some experience be just incase they get to the finals again some other time but PSG is at their peak so we not expecting any less from them.
If it's because Arsenal defeated PSG in the second leg of the semifinal matches in the UEFA Champions League that made you believe Arsenal is the only Premier League team that can give PSG a tough time, I think you are wrong because Liverpool defeated PSG in the first leg of the last 16 matches in the UEFA Champions League, and Aston Villa also defeated PSG in the first leg of the quarterfinal matches in the UEFA Champions League, but they were all knocked out by PSG on aggregate, so I believe it's not only Arsenal that can give PSG a tough time; there are a lot of Premier League clubs that can give PSG a tough time.
Let me help you with your statement they'll be Enzo Maresca's nightmare and I'll be pretty sure he'll be confused on how to rotate his squad to be able to compete well with PSG man that PSG squad is scary I'll be really surprised if Chelsea doesn't concede up to two goals or more in the first half. Anyways today the day let's keep speculating with time we'll know which team is best.
