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."
