The Gunners face holders Wigan Athletic in London tomorrow, with almost 50,000 Arsenal supporters expected to attend the game.
The striker told the club's website: "I think we are strong enough, playing in London so it's nearly a home game for us. I think it will be a great atmosphere.
"You don't fight always for one person, you fight for the club and every player that plays on the pitch gives 100% every time.
"So together we go out and play for the club and the manager and for the staff, and for all the other people associated with the club."
Arsenal last won the competition in 2005.
