The competition in the Champions League next season will be even tighter, big teams that were humiliated in the Champions League this season such as Manchester City, Real Madrid, and Bayern Munich, they will make changes ahead of next season by bringing in better players and also changing their coaching chairs like Real Madrid did. Big teams that routinely win the Champions League will not remain silent if next season PSG plans to win the Champions League trophy again. But one thing is for sure in the next season, the competition in the Champions League will be tighter compared to this season, so it will be more interesting to look forward to.
Yes, of course. But when it comes to honesty I still believe Real Madrid will be stronger next season. 
I think you know why I say this because a new coach can provide inspiration and a different strategy. Xabi Alonso has more modern tactics and strategies and with this opportunity Madrid can hope to shine again. But however I will not underestimate Liverpool, which I am sure in the coming season will definitely be more enthusiastic. And for PSG, I honestly doubt it even though they just set a new record.
