The Ivory Coast superstar has now banged home 10 goals in nine games against Arsenal.
He said: "Maybe I'm just lucky. I like to play against them because they used to be the team people support in France, so I was supporting them as well.
"But since I've come to Chelsea, I have done a job for my team."
Drog pointed at his boots when he scored Chelsea's third and explained the red laces were in support of a campaign against AIDS he is launching today.
He added: "Last season we showed we could be champions but we lost a lot of points at home and away, especially against the big teams.
"But this season we don't give any chances to opponents at home and that helps you. You get more confidence."
