Where did that form come from

Talking about Arthur here,what the hells happened to him? we all know going forward he is good and can put a decent cross in but defensively he is an accident waiting to happen but he seems to have worked a lot on that side of his game so from being a player that looked certain for the door this summer has he done enough for El Pel these past couple of weeks to keep in the squad? i have gone from someone who wanted him out to now being creosote about him mmm i sense a poll maybe needed.
