It took a bit of the direct play, they lacked in the first half to get the penalty. While VAR was working on that, Almiron wiped himself out, racing up the pitch.
It was an example of how much energy they'd used, and they had little left when they needed a goal.
Galzara is the cheater's cheat of the tournament. The ref was clearly letting a lot go. In the first half this was mostly Paraguay, but a couple of France moments too. As it went on, it was clear the ref wasn't taking accumulated fouls into account. Let alone the little kicks or those hits across the chest. But then, on one of those, Kounde went down holding a face that hadn' t been touched. The ref wasn't impressed by any of that.
Like a lot of sides, France lacked anything central, and no real desire to get a ball in there to cause problems. As the tournament goes on, that will probably be less of an issue, until you need a goal to stay in it.
Well done to France, for not getting involved after the whistle. Paraguay had to go and moan at the ref instead. I noted the Beeb saying that the they were staying with the pics, basically so they could show any fighting, then tut about it.
