During the Lyon Vs Bordeaux match, I remember the commentators mentioning that Chamakh had score 10/14 goals on the year with his head (he scored with his foot for a change that game, after a nice play by Tremoulinas).
Definitely not a good fit for our static, clueless team, but I could see him light it up at Arsenal, given the amount of service those strikers typically see - when their midfield/fullbacks are fit and proper.
