Frenchman Giroud is starting to find his feet at the Emirates Stadium after his summer move from Montpellier with two goals in his last three matches whilst Walcott is back in touch with five goals in his last five outings, including a hat-trick in the remarkable 7-5 League Cup triumph over Reading.
Ahead of tomorrow's home clash with Fulham , Vermaelen says that both Giroud and Walcott are now giving an extra dimension to the Gunners attack especially after their goals in the 2-2 Champions League draw with Schalke on Tuesday.
"I was very glad to see Olivier and Theo score our goals," Vermaelen told the Official Matchday Programme.
"Olivier is now playing regularly and has been able to find some momentum, being in the team two or three times a week. That's particularly good for a striker, and the fact that he is scoring goals in all competitions gives him a massive boost for the future.
"As for Theo, we all know what he can bring us - he is so quick and stretches the pitch really well, pulling the opposition out of shape and troubling them with his runs in behind.
"That's sometimes exactly what you need in a game - the option to put the ball in those areas for runners. Theo is very dangerous in situations like that."
