PSG doesn't have it in them to win it th second time, their win this season was a lucky one because if they had met informed teams they won't had stand a chance.
You talk like you haven't been watching the FIFA club world cup matches since the reintroduction this season. What's so extraordinary about Real Madrid? Barcelona won the laliga by defeating them, they got eliminated from the champions League in the knockout stage and you think, of course because they're called real Madrid, that's enough to win titles?
You're only rating the club from its past glories -- one of which a lot of players (and Zidane, the coach at the time) has either retired, moved on or signed for other teams. You can take it from me or hold on to your outmoded expectations -- PSG is the best club in the world right now.
Next season favourite still has to be Real Madrid
Keep dreaming!!
