I thought Rhys Williams was the biggest positive of the game – looked very assured, even more so than in the 1st game vs Lincoln, and didn't lose his confidence after Virgil went off. He looks like a leader type CB, which is so sought-after. "Minivan Dijk" is going to stick, hopefully.
Neco – like everyone said, started visibly short on confidence, but gradually improved and was playing well in the 2nd half. This was a test of his character and he came through.
Grujic was much better than against Lincoln, but should have directed at least a couple of his headers on target. C'mon, Hertha Berlin, you won't be able to buy a young midfielder of this quality for £20M in any other year!
Harry Wilson was less noticeable in the 2nd half, but I reiterate that I thought he was one of the best players in the 1st. Good energy, passing and surprising pace. Good deliveries from set plays too; too bad there were no direct free-kick opportunities.
Jones was the opposite – kind of overplayed and seemed out of sync with teammates in the 1st half, but bossed it in the 2nd.
Minamino was the only real disappointment – it seems the early caution really knocked him off his stride and he couldn't find a way to be as aggressive as he liked. Or maybe there was another reason, like Arsenal's extreme crowding of the space in the middle – but this was his first ineffective performance after a string of good ones.
