He's certainly more agile than Xhaka, that alone is a huge advantage. And I agree, Emery was probably not the coach Ceballos needed. Arteta I feel will give him a more focused game when fit. I actually thought of Ceballos when Arteta came in and thought about how he can be used differently. I think as a deeper lying player he's a much bigger threat. I can see him being used similar to Xhaka if the latter leaves.
