Adebayor is a much better finisher than Gervinho, but he's still a possession vacuum even now. Was the most wasteful striker in the league last season in terms of shots-goals or shots on/off target or some such basis. Getting Into good positions is his strength, for sure, as is his versatility in being able to score in different ways, but his technique is ropey-as a lot of the time.
Anyway, these days I can't stand strikers (or forwards) that can't finish. Gervinho included.
