I'd like to see Walcott through the middle at some point, but having got rid of all our wingers, we'd have no-one to play there. Cenk has been quite good but from the little I've seen of him, he's not the most mobile. Maybe in a more expressive team he'd bang them in for fun.
Dare I say it, I'd love to see us emulate the RS and just pack the forward line with pace. 4-3-3, balls out running for 90 mins. Walcott with 2 other similar players across the front, pace with around 12-15 goals a season in them. That was my hope last summer after losing Lukaku, but maybe we could hire a manager who would implement this kind of style.
Back on topic, as much as I like Bolasie, Walcott is streets ahead. He just needs to be given freedom to play (which is why I think up front would be good) and forward options to play alongside. Bolasie doesn't look like he knows what he's going to do next.
