PSG's system doesnt suit a soon-to-be 36-year-old Messi. They need better midfielders and two pacy, strong wingers. Messi in a free number 10 role, behind Mbappe with players like Coman and Gnabry on either sides and Leo could still deliver the good. Yesterday they played in a 4-4-2 -formation. That simply doesnt fit Leo today. Not in any way.
Eh, 442 would be fine, but a) PSG doesn't have a CF that Messi can play off b) the rest of the team sucks anyway.
