There is no doubt that they are the best in Europe, although the way things are going now it is Debatable ,The result of the Club World Cup was very decisive, Chelsea did not beat them by just 1, it was 3 goals that left them humiliated, so if PSG had been the best in the world they would have easily eaten Chelsea, these are impressive things that I like a lot about Football, without a doubt Luis Enrique gave them an unforgettable lesson, I have no doubt that PSG will be the best team in LIGUE 1.
It is obvious that the final game was a pure unlucky situation for PSG and they are still the best team in the world for the time being. I get that it may not be that great for the moment, but if they are given any good chance then we could say that it could be great. For this time being, we should be looking into a great way of moving forward with. I hope that people could focus on how to get a better return with this period so that they could make some money.
I believe things won't be as easy for PSG this season as it was last season. Yes, they are better club than Chelsea there is no doubt about that, but after one year and all these transfers from all these teams, becoming the best yet again would be a very tough ask. So PSG may not win it again, probably.
