I think of him as more functional on the ball than creative, as you say, or silky.
Would be nice to bring in a player who stays fit and contributes defensively and with goals, though. We're not exactly spoiled for that sort of thing.
I'm surprised some team playing 4-3-3 with attacking wingers hasn't bought him and tried to make him a false 9. He'd still get goals and do some work defensively. Not especially creative but he gets into pockets of space and lays it off well.
Personally, I think he might be better off in another league. He reads the game well and sometimes when that's your strength as opposed to physical attributes, it still feels like the Prem isn't always the best bet. On the other hand, if he doesn't do well in England, he can move abroad, his goalscoring record for club and country speaks for itself, and he seems like a solid professional (I've never read otherwise and he's always working hard for Canada even in annoying Concacaf environments or if the game isn't close).
