The Gunners smashed Greek side Olympiacos on Wednesday night to book their space in the Champions League last 16, and after the clash Arsene Wenger heaped praise on their all-round performance - labelling it as one of his best wins in Europe.
Olivier Giroud's hat-trick sealed the win for the north London club.
"It is a fantastic achievement for us," the Frenchman said, as Arsenal.com reported. "When you look at who we’ve lost in the last three weeks, we’ve lost Coquelin, Cazorla and Alexis among other long-term injuries, not many people gave us a chance.
"We are a real team. In the dressing room this team is very close and you could see that again today."
On whether it is one of his best European wins, he replied: "Yes, certainly because we needed a perfect performance to score without conceding. That is not easy because they are a good side."
And regarding Giroud's display, Wenger said: "It was a perfect performance because he scored a header, one with a good combination thanks to a good pass by Campbell, and also a penalty on top of that.
"He was sometimes in uncomfortable positions but he fought like mad and he has shown skill and character. I always defended Olivier on the character side because he has always had something special on that front. He showed that in the game again today."
