Bayern won their fifth European title, and first in 12 years, in May by beating fellow German side Borussia Dortmund 2-1 in the Champions League final at London's Wembley Stadium.
They also won a domestic league and cup double to become the first German club to claim the treble.
They currently have a four-point lead at the top of the Bundesliga and have reached the Champions League last 16.
In the 2013 MLS All-Star Game, Italy's Serie A club AS Roma cruised to a 3-1 victory in Kansas City.
