“The number 17 is a very special number to me. It was the number I wore as a young player, and I’ve always requested to wear 17 when playing for my country," the versatile defender said, per Arsenal's website.
“With 17 being free since Cedric left, I asked if I could change, and thanks to everyone at the club for supporting me.
"It’s also very important to say that if anyone has bought this season’s new shirt directly from the club with my name and 35 on it, they can get an exchange to my new number.”
