I think our team needs to slow down the game in general, when in possession. (And press more when not in possession). We are too hurried and headless. So from that principle, I'm OK with De Jong slowing things down. We need somebody attempting to restore sanity and calmness. The likes of Emanuelson and even Boateng simply don't think before making their pass/shot.
De Jong had a poor game last night though. But generally, I'm OK with his slowness and methodical passing.
If I have any complaint of De Jong, it is that he isn't pressing enough. But I think that's down to Allegri's tactics - no one in our team is pressing at the moment.
