20/21- Both finish 1st again. PSG got tougher draws in the Rof16 and QF, but did lose in the SF to Man City.
21/22-Both in the same group. Man City finish 1st by 1 point. They finished 1-1 in H2H group stage play.
Man City is slightly better and the only reason for that is this year's group stage. But really, both teams have been the same ballpark performance wise in the CL so far.
