He's a striker that works off tap-ins, without the class, ability, or football smarts of Jelavic. Goes missing for sections of the game and his 2011/12 has been patchy at best. Sure he played well in 2010/11, but he was found out in the next season and Celtic cannot rely on him to win them a game, that's Stokes.
There's some Nigerian mid/forward in the SPL at the moment making some noise, Sone Aluko, I'd be looking at trying to lure him down south.
