Arsenal midfielder Francis Coquelin felt they were unlucky in defeat at Tottenham.
The young Frenchman featured in his first derby performance.
"We started off quite well and we were moving the ball around. We played a good Tottenham team but we could have done better because I don't think they were better than us. Now we go home with a 2-1 defeat which everybody is disappointed with," he told arenal.com.
"Of course, I was a little bit surprised (to start) but as soon as the manager needs me I have to go on the pitch and give everything. That is what I tried to do today."
