BERLIN - Bayern Munich's main rivals failed to dent the European champions' seven-point lead in the Bundesliga with Bayer Leverkusen and Borussia Dortmund both suffering shock defeats on Saturday.
On the final German league weekend of 2013 before the winter break, Bayern were absent in Morocco preparing to take on Raja Casablanca in Marrakech in the Club World Cup final.
Leverkusen and Dortmund's defeats means Pep Guardiola's Bayern can go 10 points clear if they beat VfB Stuttgart in their catch-up fixture on January 29.
Second-placed Leverkusen fell to a late goal at strugglers Werder Bremen, whose Argentinian right-back Santiago Garcia stabbed his shot home to give Bremen a first win in six games. Borussia Dortmund's poor league form continued with a 2-1 defeat to Hertha Berlin, their third straight home defeat, which threatens to see them finish the weekend outside the automatic Champions League places.
