Mathieu Flamini felt Arsenal proved their class in victory over Newcastle United.
The midfielder is convinced they can achieve something special with the Gunners this season.
Flamini told arsenal.com: "I definitely believe we have the quality in the team to achieve something big. It's not easy to go through all these games with so many injuries, but I believe in my team and I believe in their quality.
"We knew we had a bad game in Stoke, and had a good reaction when we played away in Istanbul, which was not an easy game, but it was a good performance."
