He's actually looked surprisingly good for Derby. I think we just massively misused him. He seems to play more the Azaz role for them, not stuck out on the wing
I especially liked how fussy he was about the correct position of free kicks and throw ins, which both teams would then totally ignore. And giving their player a warning after two fouls, then letting him do several more without ever booking him.
Maybe I've missed it, but not seen any talk about the horrendous tackle on Scienza just before half time. The referee didn't even give a free kick at first. Can't even see it mentioned at the time it happened in this thread.
There was one glaring one in the first few minutes. Received the ball facing our goal, no-one within 10 yards of him, passed it straight back. He has no spacial awareness at all.
