Remember him torturing us in the 7-1 game v yourselves (Still can't forgive Paul McShane, who was directly at fault for about 5 of your goals that terrible, terrible afternoon) with his power and desire. Having said that, I think you're entire team tortured us that game, Cahill, Arteta, the tea lady etc.
Really good forward, similar to Lukaku (Although not as good obviously) in terms of he come alive in the box, and his strength, meant he just brushed defenders off the ball too.
He would barely touch the ball for like 30 minutes, then he'd pop up at the exact right time to finish off a good move. He's scored goals all throughout his career.
Seemed very popular with the fans too, 'Feed the Yak and he will score' was a popular chant was it not?
