Mikel Arteta admits Arsenal's locker room is "different" compared to former club Everton.
Arteta quit Everton for Arsenal on transfer deadline day.
"I left behind the best dressing room I've ever been in, without a doubt, with jokes and great characters," Arteta told AS.
"I have come to one that I do not know how to be, with many nationalities, more languages, younger people. And I've been very pleasantly surprised.
"I have Brazilian friends on the team, and I knew Yossi Benayoun, Per Mertesaker is a fun German."
