The kindergarten ambushes Bayern: masterful flashes of lightning in Munich, as one Dortmund photo book put it when recalling February 26, 2011. For the first time in nearly twenty years Borussia won away at Bayern Munich and took a giant step toward the league title. Goals by Lucas Barrios, Nuri Sahin and Mats Hummels sealed Dortmund's first win in Munich since 1991. Klopp gushed afterward that the last time Dortmund had won there, most of his players had still been breastfed.
