From that slow replay, Walcott as usual was terrible defensively and Coquelin, he looked around, saw the danger but stopped and didn't react at all when the ball was coming back. Too many players who do that, watch the play and react way too late.
I was saying for years now, we needed the likes of Coquelin, who was better than Song and Arteta by a mile but ignored for ages, but as a back up/rotation/apprentice. We need a 27-30yr old genuinely top dog proven DM for which younger players can learn and improve from watching and playing with. Instead we got Elneny and then Xhaka, who both have the same issue, they tend to jump in too early, be reckless and not predict the run of play well enough. They are watching each other, no one is learning from an experienced better player and none of them is progressing.
Another 35mil on a questionable DM when what we needed was the experienced player from which our younger players can watch and learn.
We had that situation where our DM was so bad that when Coquelin played people acted like he was utterly brilliant, because by comparison he was, but in reality he's no where near a top player. He's got potential but he needs to learn from a great player to improve.
