It is still too early to pick a team for the upcoming season. All teams want to win the title every season and defend it after becoming champions. PSG is no different. PSG will definitely want to retain the title next season and see themselves as champions. But the rest of the teams will not only want to see them. Rather, they will also participate in this fight and fight for the title. The list of strong teams for the upcoming season will definitely include Barcelona and Real Madrid, along with Liverpool, Arsenal, Bayern Munich and Manchester City. Although City is not in a good position right now, they will definitely bounce back once the season starts.
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.
