The Arsenal striker has scored just once in the League since joining from Montpellier for £13m in the summer. However, last term he finished top scorer in Ligue 1 as his 21 goals fired the side to the title.
When asked if his style suited playing in the Premier League, he said: "Yes but I have to be prepared to battle against some very tough and physical defenders who go for it. That's the fighting spirit you find in England. The Premier League is the best in the world and it has more intensity than the French League. You need to be ready physically and there are a lot more better players, like in La Liga."
