The former OL striker signed for the Gunners this summer in a club record deal reportedly worth £52.7 million, despite French giants PSG having and interest in him .
The 26-year-old has settled in well, netting four goals in seven Premier League games for his new club, but knows that matching his haul of 37 from his last season with Lyon will be a tall task.
"I will try my level best to achieve that but there is a big difference in that I was played in virtually every match at Lyon," he said. "Here the manager likes to rotate players to keep them fresh for the Premier League.
"I will try my best to score that many goals but this is my first season so it's all quite new.
"I want to settle in and repay the confidence that's been shown in me."
"The main difference in the Premier League is that game is a lot more physical. The pace of the game is also very different - I now really understand what it means to play box to box.
"Things can move so fast that you don't have time to catch your breath or think about the next move."
