I do agree re Rapid Vienna. He absolutely should have played that game at least, and there are a couple of games where he could have rotated with Saka when the latter was playing deeper.
I find it a bit weird but I'm not sure why either of them are being dropped in the grand scheme.
Even more weird when Arteta comes out and says Nelson has been training well. Yet Willian has been poor and Nketiah has got on before him on the right wing. So confused.
