PSG's motivation will indeed continue to increase after successfully coming out as champions and maybe in the future they will try to maintain consistency in order to maintain the opportunity to defend the Champions League trophy. But if we talk about competition, maybe next season will be much more competitive so PSG themselves will certainly get much more difficult resistance. PSG can still be one of the strong clubs next season but I doubt their ability to defend the trophy because remembering the competition in the Champions League is not easy because there are many teams who may have evaluated the level of weaknesses that will be perfected.
I see that there are a lot of skeptics around PSG who do not believe they are capable of repeating the success of last season. But it seems to me that PSG under Enrique has become a different team, they have become more conscious. Enrique added very good speed and, most importantly, he managed to achieve such great success with a very young team. He built a new PSG made up of very young players, and that is why I believe they have huge potential for the next few seasons. I even think they are capable of trying to defend their title.
As long as they can maintain their performance this season and can improve it even more by recruiting players to strengthen the depth of the squad, then it is not impossible for them to maintain their success next season.
However, this is football where anything can happen, maybe they have a very big problem such as being hit by a storm of injuries and others that make them have to decline drastically. Talking about the coach, Enrique has good capital, because logically he should have understood the squad he has better, so that should be able to help more.
