He scores against Liverpool all the time man. And I remember at least 4 goals against Arsenal since 2007. I only remeber 1 goal against Man U since 2007 (FA Cup final btw). So you're talking complete nonsense, basically.
Find it funny that you even dare talk about strikers unable to score against the top teams, given your embarrassing love for Owen.
EDIT: Drogba's last against Arsenal was his 8th in 9 games. :lol:
He has scored something like 3 in his last 12 games against other top teams. Torres ratio is a lot better.. check for yourself. Drogba scores most of his goals against the dross of the league... explains why he scores against Jamie Carragher the odd time or two.
Mate, look for yourself at his record in his last 10 games against Liverpool and Arsenall in all competiitons, it's fantastic.
