Arteta was asked whether he spoke with close friend Xabi Alonso about beating the German champions.
Alonso's Bayer Leverkusen are top of the Bundesliga this season and are only a handful of points away from the title.

"I'm not going to answer that," he said in his pre-match conference ahead of Tuesday's fixture against Bayern in the Champions League.
On Bayern, Arteta said: "Top team. I'm a big fan and big admirer of Thomas (Tuchel), his teams, the way they setup and play, what they transmit.
I've learned a lot about him and looking at Bayern, when you analyze them deeply, you see why they're a top team.
"We've prepared very well and we have to take our game where we want it. If we do that we have a chance to win."
