The Frenchman has enjoyed a good week for the Gunners, first bagging a hat-trick against Olympiacos in midweek before scoring a penalty against Aston Villa.
That goal against Villa took him to nine in 16 this season, making him their highest goal-scorer so far, while it was also his 50th ever in the Premier League.
He has more than stepped up and proved his value to the side in the midst of their recent injury crisis, and Walcott has described him as a dream to play with.
“It’s not just his goals, it’s his general play and everything about him,” he told arsenal.com.
“The way he holds the ball up, he blocks it and defends it, and he works hard from the team from defensive corners and everything.”
“He’s in great form at the moment. He’s a dream to play with and he makes our job a lot easier. As soon as I won the penalty, I just knew that he would score.”
Much was made of Arsenal’s failure to sign a top class striker in the summer, with manager Arsene Wenger bearing much of that criticism.
So far it has not been something that has backfired though, with the Gunners currently the third highest goal scorers in the division, with Giroud fourth for individual goals.
With the French international in this kind of form, it is fair to say Wenger was justified in not signing another striker and sticking with what he already had.
