He just seems clueless at times, he's not equipped to handle teams with star players. When I see how he's managing Messi so far, it's beyond belief. He had Messi as an out and out winger one game, and false 9 up front on his own the next, that's someone who has absolutely no idea of what he's doing. There is still no philosophy, consistent passing and patterns of play 11 months in. I've held back last season when he took over for Tuchel because I feel every manager needs at least an off-season and some time to apply their tactics to the team, but there aren't any. He's relying solely on the individual brilliance of some players, as so far it's mainly Mbappe, Hakimi, and Di Maria to a lesser extent (shout out to Gueye and Herrera) that have been able to answer the call consistently. Without those three and Navas/Donnarumma, this team is not top of the league.
The excuse of not having a consistent XI to work with, which I've brought up in the past is only fair if the manager is just coming in, but he was here for months prior to that and the team still looks as clueless. I could count on one severed hand how many times PSG looked superior to their opponent. He needs to find the formula very soon because his days are numbered at this rate.
