It is funny out of all 3 potential penalties, only the one that is not one is given as a penalty.
Still PSG doesn't have the gear to handle low block, but they improved from last game that's why went from 4-1 to 1-1; they learned how to get the ball across midfield, handling the pressing, better movements for that, so conceding less; but they simply don't have a big man, clinical finishing, small area drills (you can tell by seeing them move to keep possessions, but not attacking), neither are they good at creating crossing opportunities or have methods to stretch compact positions (or switch sides and hit them at position transferring), normally I would blame PSG as the whole organization, but clearly Enrique has no gameplan for the final third, most of the "chances" were created by individuals' brilliancies, but moving Mabappe to the mid and cut in with the wingers did some help, but they are wingers so you get that kinda finishings.
