goon I can only assume it's load and expectation management given just how much Arteta raves about him as a player.
We've been playing like shit, and Saka is Arteta's go-to match winner and he's got a long history of leaving Saka out on his legs hoping to squeeze out results. And that is why we haven't been seeing too much of Nwaneri.
Plus Arteta felt like he needed to work through all his other senior options out there, even though they've all been less effective than Nwaneri.
