It is not certain whether PSG can do better next season. However, by the PSG performance so far, I think the team is getting more stable and stronger day by day. Luis Enrique has trust of his young players. PSG will be stronger if young players become slowly experienced..
Of course, there is no guarantee that PSG will also be the winner of the next UCL championship next season, but of course this UCL victory will boost the all-winning spirit of PSG so that this time, they will be much more prepared and stronger than before.
PSG players will be confident next season after winning the Champions League this season. So for the Champions League title, the PSG team will be considered as favorites next season. Also, since PSG manager is Luis Enrique, the team will undoubtedly fight for the Champions League title next season. Lewis Enrique will take all the necessary to strengthen the PSG squad. At the same time, PSG's management does not make any money at the cost. Since Luis Enrique has brought good results to PSG, PSG management will undoubtedly provide large funds for player purchase to Luis Enrique.
