The defender arrived in the summer from Lorient.
He told Arsenal TV Online: "Of course, there are many Frenchmen around the club and it's been a great help having them around me when it comes to settling in. Everything is going well.
"It's true that the Premier League is hard physically and is more intense than the French league.
"So, in that respect, I've had a big jump in standard. But, I will keep working hard in training and I think soon I'll get used to everything."
