Re: Theo the upside has been shown, and the (radical) differences in their play/what they offer needs to be taken into account.
Re: Ox I don’t necessarily disagree, but there’s simply no denying the fact that Ox has more natural ability than Campbell. I’m not really interested in arguing between what’s more worth it, proven decent-ness or current shit-ness with a chance to be a little better than decent-ness. In an ideal world Campbell would be willing to accept his current squad role, and we’d just have a better player than Ox and Campbell in Campbell’s place. In the real world Campbell wasn’t interested in continuing to be a squad player (which is what his role should be at a big club), and Wenger persists with Ox instead of cutting him loose and buying something better/or giving a chance to someone like Gnabry who certainly would be better and deserved the chance more.
