In Tuesday's big match, Bayern Munich edged Arsenal, 2-0, on second-half goals by Toni Kroos and Thomas Muellerfollowing a first half that saw both teams miss penalty kicks and Arsenal keeper Wojciech Szczesny set sent off.
Fellow Pole Lukasz Fabianski came on for Szczesny after his red card for a foul on Arjen Robben in the 39th minute, but he watched as young Austrian David Alaba smashed his shot off the left post.
Arsenal's chances effectively went up in smoke in the eighth minute when Mesut Ozil had his penalty kick saved by countryman Manuel Neuer.
