For now, Luis Enrique is focused on winning the Club World Cup with PSG, and his intention is not to sign players. Let's just wait till the Club World Cup tournament ends on Sunday; then we will know if Luis Enrique is interested in signing players this season. If Luis Enrique doesn't want to sign any striker, it is a good choice for him and PSG because I don't see any reason why Luis Enrique should sign a striker for PSG when all the PSG forward lineup is capable of scoring goals.
PSG are not in urgent need of new signings, if teams are in need of using the window then PSG are far behind because they currently are holding the best team performance in the world for previous season. The players in PSG are capable of doing what they did last season, after winning Champions League, most of us thought it was the end of PSG dominating competitions, but they proved themselves during the whole games played in Club World Cup, no team is really a match for them and on sunday when they will face Chelsea in the final, it will be a day for another trophy.
There's no doubt about PSG performance at the moment. They've eliminated Inter Miami, Bayern Munich, and Real Madrid, and they should easily beat Chelsea as well. From the round of 16 to the semifinals, PSG have scored 10 goals and conceded zero. I think these statistics are very convincing and demonstrate their unstoppable strength, including Chelsea in the final.
PSG, once often underestimated, has now transformed into arguably the best team in the world. No one dares to underestimate them anymore. Luis Enrique assured PSG fans that they will be truly happy this season, and that winning the Club World Cup would be a truly memorable end to the season. I think Chelsea will need a lot of luck to win the trophy, as PSG are clear favorites.
