I just wish Defoe got involved in our build-up play more. Watching Emirates Marketing Project vs Southampton, all four of their front players showed for the ball when their CMs or FBs had it. With Defoe, I think it's sometimes harder for us to get the ball into the final third because he's normally on the shoulder of the last defender. He has the physical and technical ability to be able to drop off a centre-back, receive the ball, hold the centre-back off and then release it to another player; THEN he can try and get into a goalscoring position. When he hangs around the defensive line when we have the ball in deeper positions, it's just not very useful (unless we consistently manage to play him in over the top from deep, which is very hard to do.
IMO he's better technically than Adebayor (in terms of touch, shooting, close-control etc), but Ade (as well as some physical advantages) just has far better and well-rounded movement.
