Flawed, yes. Arsenal fans will learn that in time.
But absolutely the best back-up striker anyone could ask for. He worked hard, he scored goals (most of the time), he scored some particularly important ones at that, and always kept his mouth shut when Aguero was in front of him.
Never quite realised the potential he showed at the beginning but his G/A rate was really impressive and he was a big part of the reason why a transition to a false #9 system was so easy for us to carry off. Wish him all the best.
