He can come on in the middle and play off a striker in a 442, he can come on either wing as a sub, he can start either wing, he can start in the middle, he can start as an AM, he can come on as an AM, hell he'd be an option as a lone striker if we're chasing the game and need to try something different.
Walcott is never fit, Chambo is constantly getting knocks and niggles and can't last a full 90, Wilshere is hot and cold but I think he'll probably nail down a spot next season, Poldi is frustrating as fuck and shouldn't start for us, Gnabry is a kid with no experience, loan him. Ozil can't play every game for the full 90 either.
He'd get "regular minutes" because he'd merit them ahead of Rosicky, Gnabry, Sanogo, Giroud, and Podolski while competing for a starting spot with Chambo, Wilshere, Santi, and Walcott.
