What we need from our forward is not just goals when we're already comfortably winning, which is all he does, but goals when we're struggling, when we need someone to step up and change the game. Anelka won't do that, but Drogba has the ability and the strength to do so. That's the difference.
Anelka can score all the dodgy hattricks he likes, until he starts scoring goals against the other top teams and when we're struggling, he'll always be second rate to me.
