PSG won the Champions League title last season and it seems that they are ready to fight next season with the same team they performed with last season but my question is will PSG be successful next season by competing with the team they competed with and succeeded with last season? The big teams could not do well last season for some reason but those teams will perform well next season which will make it difficult for PSG to win against those big teams with the current team they have. I think PSG does not need to change many players in the team but they should buy some players. If they recruit some players to their club then their team will be stronger next season than last season and in that case they will be able to compete against any team but it will be tough.
PSG made their club strategic changes since there seasons ago and they have maintained it from three seasons before winning t a first Champions League title in their club history. They become a second French club that have ever won Champions League title after Marseille in 1990s.
PSG did this milestone with many young players who potentially improve themselves more and become better players in future seasons. So PSG don't actually have urgent need of buying new players in this summer but perhaps they will try to find and sign. with some young players as part of their long term developments.
