Bastian Schweinsteiger gave the hosts an early lead, and when Arjen Robben doubled Bayern's margin late in the second half, the Bundesliga giants had an easy 2-0 victory over visiting FC Zurich in the first leg of their UEFA Champions League knockout round tie.
Schweinsteiger's goal, headed in off a Phillip Lahm cross at the eighth minute market, looked to open a flood gate for the dominant Germans, but their Swiss opponents were able to hold Bayern at arm's length until the 78th minute, when a left-foooted curler from Robben found net in the goal's upper-left hand corner, giving the hosts their 2-0 margin.
Elsewhere, Odense pulled a mild upset of visiting Villarreal when Hans Henrik Andreasen broke a scorless tie in the 84th minute, giving the Danes a 1-0 lead going back to Spain.
Dinamo Zagreb posted the day's most convincing result, a 4-1 victory over visiting Malmo. Malmo had advanced past Glasgow Rangers to make it to the final play in round, but goals in the fourth and 60th minutes from Sammir helped give the Croatian champions an easy first leg.
Second legs take place next Tuesday, August 23, with the ties' winners advancing to the competition's group phase.
