Arsenal boss Arsene Wenger was delighted with two-goal Olivier Giroud after their FA Cup win over Middlesbrough.
The Frenchman struck both goals in the 2-0 win.
"We controlled the game from the first to the last minute," Wenger said.
"They had one chance at the end from a header, but overall I'm pleased with the way we attacked, the way we defended and with the way we played together with a good focus for 90 minutes. That's basically it.
"I believe that he (Giroud) is a different player today than the guy who arrived here. He understands what top-level football demands, works with a great concentration in training and he has improved tremendously on his mobility, his technical quality and of course his body is very strong. He uses it very well."
