"I tried [to score]," he told Eurosport. "I try all I can but sometimes you need to keep the faith and keep going. Sometimes when you are a striker it is difficult.
"I don't know why, but I try to do the right things. I think I am a little unlucky and sometimes I need to score. I don't score but I am okay and I keep going. I continue to work hard in training and keep the trust.
"We won and the boss (Arsene Wenger) trusts me, my teammates too, our fans too, and I want to continue. I feel good in this team. It's okay, I continue to work harder and to score and to give a lot of pleasure to our fans."
