Veteran striker Kleindienst had a memorable game here, scoring two of the Heidenheim goals as they roared back for a win. But the real winners from this contest might just be Arsenal. Mikel Arteta's side have endured some miserable Champions League ties with the Bavarians in the past, infamously falling on the wrong side of some heavy defeats, including two 5-1 hammerings in 2017. This time, though, there might be room for optimism. The Gunners are humming, and Bayern are looking as weak as ever. It might just be time to exorcise some demons.
