Like we said before, Lyon are continuing in the Ligue 1. They barely managed to remain. Therefore I assume they won't be able to make much of a signing this summer. You know their finances... They might even have to sell more players.
Luis Enrique is currently very satisfied with the performance of Dembele, Kvaratskhelia, and Desire Doue up front, while he also has quality rotation options like Goncalo Ramos, Kang in-Lee, and Bradley Barcola. Therefore, I don't think PSG will sign any star players this summer, although Osimhen and Gyokeres are worthy targets.
Even if Enrique does recruit new players, defense will likely be his focus this time, with the goal of having a better second tier player. Overall, PSG has excellent squad depth and is well balanced, it's almost hard to find weaknesses in the team right now.
Yeah the only thing they can do now is to improve the squad depth. Not to have big problems when they face serious injuries...
Mukiele has such injury now for example. Hakimi is Enrique's first choice of course but maybe he might think of a loan or something to be his backup if Mukiele isn't expected to recover for months.
