I think PSG's golden era is over. After winning the Champions League last season, they looked unstoppable. But in the FIFA Club World Cup, they unexpectedly lost two matches. The most surprising of them was the final match against Chelsea.
Yesterday's match was also unexpected. Although the good news is that PSG finally won, they had to fight hard for that victory. I thought PSG would get an easy win and start the season great. But they didn't start great and won against Tottenham. Tottenham played great, but they couldn't win the match in penalties.
I am sure when they get into momentum again, and play at league, and start winning, they will get better again. Right now they have been very tired, they played so many games, winning most, and they ended up with 4 titles so far. They won their league, they won their cup, they won UCL and they won Super cup, and they were finalists for CWC as well, which means that they played so many games, more than most other teams.
Maybe they may not be that great this season, but they will definitely end up with a good result eventually, maybe instead of this season, they can be better the season after that? Basically they just need a summer where they do not play, but most these players will go play at national teams, so it may not work out for them again.
Yes, many times these teams that win so much need to have a bit of rest, like everyone else, it's not easy to stay at such high levels for so long and it's normal to have moments of very high pressure and not be able to manage them, it's clear that they will come back stronger than before, give them time.
