Paris Saint-Germain is still performing very well. They've reached the CWC final and are close to winning the title. I'm sure many are expecting them to win the title after the Real Madrid match. While Chelsea is a strong team, I don't think they can resist Paris Saint-Germain. With that in mind, I expect Paris Saint-Germain to have another excellent season in the French league next year. Luis Enrique will certainly make time for transfers, but their squad is such that it doesn't even seem necessary right now.
PSG is currently on another level right now, and no European club has been able to match PSG's energy in the Club World Cup, so I believe they will defeat Chelsea and win the Club World Cup. Even without PSG dominance in the Club World Cup tournament, everyone knows PSG will surely have another excellent season in their domestic league next season because PSG has dominated the French league and built up a squad that's unmatched in the French league, which always allows them to win the French league title almost every season.
