I know that Liverpool will sign players when the transfer window reopens again, but they won't be as active in the transfer window as their rivals like Manchester City and Manchester United will be because Liverpool's squad is okay, and Arne Slot has few positions to strengthen in his squad.
Liverpool squad is not as okay as you may think, no doubt they were able to win premier league but if take time to reexamine there performance in the uefa champions league you see that the club is not okay.I think they will as active as Manchester city you just mentioned in the transfer window.Because this coming season will definitely be challenging for them both in domestic league and uefa championship league.This squad you are talking about can't be compared to PSG squad so definitely they will making use of the transfer window just as Manchester city you made mentions of.
