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.
PSG don't need the kind of luck Chelsea needs to win the Club World Cup. PSG are full time capable of defeating Chelsea without breaking a sweat. Even first half of the match, there should be already 2 goals at the back of the net against Chelsea. In attack Chelsea seems weaker, mid field lacking creativity and defense may not be able to stand against PSG strikers. The odds are not favoring Chelsea, PSG are confident on their victory.
