Arteta admits Arsenal's European pedigree was a big reason why he joined last season.
"To play in those big games is a great experience and I don't regret the decision. It improves you as a player.
"It's a good test to see where you are. Sometimes you think you are playing unbelievable but then you play in the Champions League against top players and you think: 'I've got a lot of work to do'."
