It is possible PSG can still the win the UEFA Champions league tittle second time in a roll, winning this pretigeous tittle back to back has been difficult in the past after Manchester United won it in 2008 against Chelsea they try to win it again 2009 against Barcelona but unfortunately they lost before Real Madrid later broke the band so I believe another team can still do it besides PSG performance last season was a thing of surprised to people and they are still playing very well so i won't be surprise if they do same thing this coming season, nothing is impossible in football.
It would not be surprising if PSG dominate the Champions League next season. They have this ability. The players are very talented, the bonding between the players is strong. At the same time, PSG also has an experienced coach like Luis Enrique. Moreover, the PSG management also has a lot of money to strengthen the squad.
Luis Enrique will want to win the Champions League title next season. However, winning the Champions League title for two consecutive seasons is really difficult. Because we can see that Liverpool, Barcelona and Real Madrid are strengthening their squads. These teams will also fight hard to win the Champions League title next season.
It is very difficult to predict how the teams will perform next season. Almost every big team has made changes to the squad. However, we still do not know which team will be able to perform consistently well next season.
