Regarding Xhaka, I just didn't think he is as much as a liability as you guys do. He was a liability when playing the Deep lying Playmaker role and clearly at times cost the team points. I think he can be upgraded on and I question his position in the team long term, especially now he is playing further forward. However I think Arteta moving him further up the pitch masks his deficiencies. I am somewhere in the middle with him. I don't think he is a liability but I am also not sold on what he offers the team (even though he is playing well at the moment).
