This is exactly what I thought, there's something about his body language that doesn't come over well...not sure what it is. I said that in a previous thread of his as well where he didn't manage the game well at all.
In terms of performance, I actually thought he was OK, by and large. All the big decisions he got right, bookings were OK for our side at least but he should have probably booked a few more Posh players (especially the handball for the penalty). And he kept the game flowing as best as possible, despite our glorious, glorious sh*thousery.
