He's been playing centrally behind the striker, seemingly with the instruction to link play and break in to the box - try looking at his performances rather than just his goals scored tally and you'll see a player who is dropping deep to link with the central two as much as he is playing behind the forward - swapping positions with the left sided player also at times too - but as he's grabbing the headlines for his goals and combined with the fact we know him as a forward then it's easy to understand where the missunderstanding lies.
