I thought he played well. Gave us physicality that matuidi does with more skill and I think when space is provided he will have space to use that cannon. Also it must be said that Ronaldo is on an island on the left while the right side seems much more fluid
I guess I will never truly understand the rules of this sport.
I see him getting the ball and then the man. Now, the ref will make a stand on a scale on how reckless that might be and evaluate what to do. It always become very subjective. Back in the days, and still in PL for instance, the rule is clear:
ball -> man = no foul (no matter if the man breaks his leg)
A note on Rabiot:
He offers something else - he's very direct. He's got that thing where he's not afraid of risking the possession. Look how he's constantly looking to get in between the opposition players. Sometimes it looks like the defense has closed down, and yet he tries to get in between. And sometimes at success. That is something any big team, being closed down, needs. Dribbling and touch is superb. With time he can become a class player. But he's still a little rusty.
People are underrating him, Sarri should give him minutes after his ban he will be one of our best players. Rabiot was the main reason why we started to dominate the match against Genua after he came in and Matuidi went out.
Look at this, he bossed the midfield against Barca and made Messi-Suarez-Neymar invisible in that match.
