"Yes, I think it helped [that I was a relative unknown]," Squillaci told Arsenal TV Online.
"I knew a lot of the players and there are a lot of Frenchmen here, which always makes it easier to adapt. There are players here who I have played with for France and also against in the French league and that makes coming here not so hard.
"It's always better coming to a club where you know the players, it helps you if there are any problems and also helps on and off the pitch too.
"Adapting-wise, I knew that it [English football] would be physical with some good sides, playing good football. The strikers are big and strong and it is a great contrast with Spain where the strikers are faster and not so strong. But it's not going too badly. I'm stepping up to the challenge and it's getting easier."
