Their good performance gave them lots of rivals last season and some would be coming back for revenge this season so they need to be prepared for the challenge ahead it's not going to be easy cause Chelsea has exposed their weakness in the Club World Cup but I trust PSG to tackle that error, I'm suprise they didn't make much signings though.
Luis Enrique needs to strengthen his squad for the battle that's ahead of him, but if Luis Enrique decides he's not signing any player this summer, the PSG squad is still in pretty good shape, and Luis Enrique can compete in the UEFA Champions League with it and get good results. I heard PSG is interested in signing Rodri from Manchester City this season, but I don't know how concrete the news is.
This player should work hard with his performance in such a way that he does not have to weaken at any time, which will also give him a lot of advantage in the match. If he wants to improve even more, then he should sign, we know how well PSG is maintaining itself. For this, he will have to improve his performance again and later he will be successful in this league due to his ability and hard work. So this also improves PSG's performance, but it is not clear because Josué Kasse has said that PSG has no particular interest in him, which is why this signing is a rumor. According to me, this news is meaningless and if it is true, then this is a very acceptable good player.
