It doesn't matter how long PSG have to wait and how much money they have to spend, but as long as they can still qualify for the Champions League every season then as long as they have a chance to win their first title.
Teams like PSG have a better chance because they can build their quality team with experienced and good quality players. Compared to many other teams, I think PSG have been on the list of favorites for the title every season even though they always fall short. There will come a time when PSG can win their first Champions League title, so Luis Enrique might be able to help maintain that chance or maybe he can fulfill PSG's dream of winning his first title.
Numerous teams are warming up for the new season, no time for relenting efforts. The Parisians have had their sights set on the trophy for an extended period of time. Every season is an opportunity to succeed for them to try again and refrain from giving up. As an illustration, Manchester City persevered in their pursuit of the UEFA Champions League trophy; today, they are the reigning champions. PSG requires perseverance and dedication. Luis Enrique would perform better in his new club; he is aware of the team's issues and plans to address them in the upcoming season.
