Ramsey does his bit. He was leading every opta stat around last year inc. tackles and interceptions. He's not the most savvy, but because of his ridiculous stamina his numbers are always good. Wilshere and Cazorla have a bit more awareness but much less energy.
With Coquelin next to Ramsey we'd be ok. Cazorla has done well but his contribution to our winning run is slightly overrated imo. He 'sits' and gives the illusion of helping us hold some shape but it's only because he can't run quick enough to join attacks. And when he's not hitting a dead ball, he's utterly useless near the box now. Similar to arteta in that sense. Cazorla doesn't hit many penetrative passes or open defences. Performs the same role as Coquelin with slightly more accomplished footwork.
