Arsenal signing Olivier Giroud is convinced they can silence their critics this season.

Giroud was the joint top scorer in Ligue 1 with 21 goals and also contributed nine assists in a memorable campaign. He believes that Arsenal have the quality and mentality to emulate Montpellier and upset the Premier League favourites.

"It's true that it was an extraordinary season with Montpellier," Giroud told Arsenal Player. "I won't ever forget that season because in a footballer's career, winning the title isn't forgotten so fast.

"There was a good mentality in the team, good quality, with some good players, and I look forward to finding that quality and spirit with Arsenal - that's why I chose Arsenal.

"With Montpellier, it wasn't written that we were going to be champions, so that's what made it more beautiful. With Arsenal, we might not be favourites, like the Manchester clubs, to be champions. We're outsiders, but I'm convinced that we can do something big. That's what we did with Montpellier, and I'm proud with what I accomplished there."
