Moreover, I see PSG also not really dominating throughout the competition in the Champions League. They have to work hard to get the title. All teams are improving and preparing the team for the competition. We have to see the development of some strong teams that will also compete. Their performance in the league will definitely give us an idea of how they will compete in the Champions League.
You are right, PSG has to improve more if they want to lift the champions League title again next season because other teams are really fighting hard to make sure they increase there form, next season clubs like Barcelona will be on fire because they will be very strong and inform, I'm hearing they are going for a very good player to add to there squad and that is a very good one, however PSG is very much inform and all they need to do is increase there from a little bit and they will be good to go.
For me I think real Madrid, Barcelona and PSG are the clubs that may likely lift the next seasons champions League trophy, real Madrid will grow stronger I'm sure this there New coach will make them improve but it won't be that easy for him since his just coming to the club newly but with his experience I believe he can work with them immediately, real Madrid has good players they just need to use or come up with a very good formation.
I understand the concept, I understand why "getting better every season" is something every team should do. But I am not exactly sure if this should be the way PSG should move. Because they already have something that works, and making changes could hurt them a lot. If we could make sure of them doing the same thing that they did this season, they can't make any changes.
If we could see something changing and they get some players and what not, then what is working right now, could be broken and I would suggest them not to do that. If they want to win it all again, which they did, they had a treble, then all they have to do is keep the team similar and work harder. If they do that, then they have what it takes to win again, they showed us that.
