Bayern chastened after loss

Bayern Munich's director of sport, Matthias Sammer, says the Bundesliga leader must learn to keep its cool after suffering its first German league defeat of the season at Borussia Moenchengladbach.

The Bavarian giant lost its unbeaten record in Germany's top tier when it suffered a shock 3-1 defeat at Borussia Park which cut its lead in the table to five points.

It is only the second time Pep Guardiola's Bayern has lost this season - having gone down 2-0 at Arsenal in the Champions League in October.
