Yeah this is pretty much it... he has gotten better in a few games, games where the team has overall functioned slightly less shambolically. He is better than Ramsey, but I am better than Ramsey tactically so that isn't saying much. Our options in CM are actually pretty meh right now and that is sad as it used to always be one of our strengths.
Speaking of stats, Denilson often showed up really solidly in stats because the way we played and his style/role were always going to produce those inflated numbers - it is such lazy analysis to take stats like that out of context without the bigger picture.
The one thing that all our players need to learn to do better is micro-positioning... Xhaka has adopted the Arsenal habit of just managing to get on the wrong side of the opposition player on a regular basis and we don't seem to know how to avoid that or react more intelligently when we do - we often then tackle from behind, nip on the side, or generally bounce off the opponent because we don't have a good angle on the ball or a way to steer them towards defensive support. Ramsey is perhaps the player who does this the worst I have ever seen at the top level - it is farcical how reliably he gets wrong side.
