daredevil That's the thing I'm wondering about whether it is by design or not. When he had that great season he was coming in and linking with Xhaka and getting into the box more. Even his crossing was similar to what Saka does from the left, the Odegaard goal against West Ham toward the end of the season comes immediately to mind.
It's like with Xhaka and Zinchenko gone we've gone a different way of playing and that it requires Martinelli to hold width and try to get to the byline. I can't imagine it is going against what Arteta is asking of him otherwise he wouldn't be playing.
