Giampaolo Pazzini is happy to keep fighting for his place at AC Milan.

Pazzani hit a double in victory over Lazio , taking his season tally to 12 goals.

"I always have to prove myself," smiled Pazzini. "I scored 12 goals because I was put in a position to do well and I am happy.

"We're in good shape, so must keep on picking up as many points as possible and never give in."
