The in-form France striker netted a brace for the second time in a week as Arsenal beat Brighton 3-2 in their FA Cup fourth-round tie at the Amex Stadium.
It was a tough test of character for Arsene Wenger's side, who eventually came through after the introduction of England duo Jack Wilshere and Theo Walcott, whose deflected effort with five minutes left proved decisive.
Giroud maintains if the Gunners are to force their way back into the top four of the Barclays Premier League and look to continue their FA Cup run in the quest for a long-overdue trophy, they have to produce the same efforts in every game.
He said: "We didn't start the game as we wanted because we didn't put in a good commitment and not really enough determination.
"I play better not when I am angry, but with determination, this is very important in football.
"When you don't have the hunger you can't play very well and succeed. You need it.
"It is very important for me and for all of the team, and you saw it again against Brighton.
"We want to get six points against Liverpool and Stoke to reach Tottenham and fourth place (in the Premier League), then we will play and see where we get."
