i agree with what you say, psg can be a good team, right now they probably have one of the most in-form teams, but sometimes it can be reversed in 1 season. every good period will come to an end, just like every bright morning has a night. some teams can keep it up for much longer, but i don't think a team that won the first champions league in the history of the club can win more in a series immediately.
We should expect more from Paris Saint-Germain next season. They shocked everyone when they won major UCL trophy. Winning an elite team, a dependent formidable squad is involved, craving for eligible standards and streak winnings. A good team will always end up with trophies, it's facts. We should thank Luis Enrique for everything he's had done for Paris Saint-Germain. Paris Saint-Germain are eligible and deserves what they got this season. Achieved quite alot with treble, what more can a club pray for?
Normally, when a team is able to win a competition, it is still possible for that team to win in the future again. PSG winning the Champions League last season at least gives them that winning mentality as a club that is capable of winning the Champions League. I know PSG still has chances of winning the Champions League in any season soon, but I can't say they will win this season because the Champions League is a very tough competition in which you can't even predict which team will win.
