You're both obviously right. I still think it's interesting, as I think the right wing backup minutes are up for grabs the moment Bolasie leaves.
It's an option, yes, but he doesn't really have the pace to play out wide consistently - nor the physical stature.
He will probably get a chance out wide during pre-season, especially if Bolasie is off and Walcott remains injured but I'd wager that most of his time comes centrally whilst Vlasic's pace makes him the other and actual wide option.
