Arsenal boss Arsene Wenger was delighted with two-goal Olivier Giroud for their FA Cup win at Brighton.
The France international offered Arsenal a real physical presence at the spearhead of their attack here.
Wenger said: "It's good for his confidence. He's scored four goals this week and he had a few more chances today.
"Giroud gets there. He has a presence in the box. He is dangerous and his physical presence was very important."
