Second-half goals from Toni Kroos and Thomas Mueller gave holder Bayern Munich a 2-0 victory over 10-man Arsenal and firm command of their last 16 Champions League tie on Wednesday. Kroos scored in the 54th minute, curling the ball past Arsenal goalkeeper Lukasz Fabianski, who came on after Wojciech Szczesny was sent off for fouling Arjen Robben. An unmarked Mueller scored with a powerful header from close range in the 88th. Both teams missed penalties in the first half, with Arsenal playmaker Mesut Ozil shooting straight at Manuel Neuer and Bayern midfielder David Alaba clipping a post. Szczesny was sent off in the 37th minute for following through on Robben. Arsenal hopes it can repeat last year's winning performance at Bayern in the second leg on March 11.
