After winning a title, a certain confidence usually builds up within the team. But it would be very foolish to continue playing with the same team. Because everyone else will understand their tactics and weaknesses. It would be very difficult for PSG to win the trophy twice at the same time.
But when it comes to Barcelona, I can say this. They were a very good team before and still are. Barcelona's game is never the same. They change their tactics again and again. They go out on the field to win perfectly. But it is not always the same. In all kinds of sports, luck is needed as well as skill. Football is no exception. But, this time Barcelona will try their best to make the trophy their own.
In my opinion, the biggest benefit PSG gained from their success last season is the improvement in the team mentality, which will give them great motivation when they compete for trophies again next season and beyond. Winning back to back Champions League trophies is certainly not easy, but I think PSG has a good chance of doing so. Luis Enrique is highly experienced in reading the dynamics of competition, and he’s also quite a genius when it comes to preparing different strategies for each challenge.
On the other hand, I think Barcelona deserves to be among the favorites to win next season. They just need more luck than last season to reach the final, even though Hansi Flick hasn't been very active in recruiting new players in this summer transfer window. However, with Real Madrid current squad overhaul, Barcelona will likely face greater pressure in La Liga, which means they need to work harder to stabilize their performance in the Champions League.
Yeah, being the current Champions of the tournament makes them one of the top contenders, it qualifies them automatically and their major target would be trying to win it again, they'll want to join the category of teams that's won it consecutively, you know, it's a good record so they'll go into the competition this season with similar mentality as the previous season but with a new motive.
Enrique is someone who dreams big, one of those coaches who loves to set records in any league they're in, so he'll come up with new ideologies for his players an upgrade mentality that would motivate them to emulate last season's success rate. Sure dear Barcelona is on team that I strongly believe would be top contenders this year, they were so close to reaching the finals last season so I believe they work more harder to reach it this season, the only major problem I think Barcelona has is their defense they're not very balanced in that area yet.
