It will still be a big challenge for PSG to perform well in the Champions League next season, because apart from PSG still having to get some of the best players, the PSG coach himself must also be able to bring better changes to the players at PSG so that PSG's strength is to compete in the League. Champions can increase even more because it's time for a team as big as PSG to get a title in the Champions League by beating teams that have been successful in the Champions League in previous seasons.
Seems not difference with PSG performance in Champion League actually after losing Lionel Messi and Sergio Ramos, not clear with Mbappe future pessimistic with PSG chance can lead or become the winner next season. Have experienced head coach who winning Champion League tittle with Barcelona can't guarantee will bring success achievement for PSG because they don't have solid squad next season. PSG hasn't striker right now actually with Mmbappe not sure will stay for next season or not and Luis Henrique as soon possible need some players as center striker.
Huge pressure in Champion League actually with other favorite teams success sign many potential player for next season, PSG current transfer not sure they will be the winner next season in Champion League because hasn't new striker.
