Yeah the are both really different players and will be useful at different times. Up to Arteta to get the best out of the squad
Using 2 inverted fullback makes it easy to use the 2323 formation in attack which I think is what Arteta wants as one of the main structures of play, and is pretty prominent for positional play from what I have read.. it has also let Xhaka push fwd a lot more, but KT will still be really useful when we want to put pressure/overloads on the left and he is a better defender obviously. Not quite convinced with Zinchenkos defending right now but still early days. Great options to have
