Xhaka has been a massive problem. A good manager would spot that and spend this week digging deep to find an alternative in the market. Wenger won't. If we do anything, we will panic buy another light weight, creative player like draxler or mahrez which won't solve the problem. Although I suspect Wenger, stubborn goat that he is, will dig in and stick to the line that his wonderful squad is perfect and doesn't need strengthening.
