Robert Lewandowski scored his 12th Bundesliga goal of the season for Bayern

Bayern Munich will head into the winter break three points clear at the top of the Bundesliga following an emphatic win over second-placed RB Leipzig.

Goals from Thiago and Xabi Alonso put the home side firmly in control before Leipzig's Emil Fosberg saw red for a nasty foul on Philipp Lahm.

Robert Lewandowski made it 3-0 from the penalty spot after Leipzig goalkeeper Peter Gulasci had fouled Douglas Costa.

Lewandowski was denied twice as Leipzig kept Bayern at bay after the break.

It is just a second league loss of the season for Leipzig, who are in their debut Bundesliga campaign.

Formed in 2009 when drinks manufacturer Red Bull bought the licence of amateur club SSV Markranstadt and changed their name, Leipzig have achieved four promotions in seven years to reach the German top flight.

Under coach Ralph Hasenhuttl, they won 11 of their first 15 matches, including a victory over last season's runners-up Borussia Dortmund.

Emil Forsberg has been superb for Leipzig this season, scoring five goals and providing eight assists

However, they were emphatically put in their place by the reigning champions, who were fortunate not to fall behind early on when Yussuf Poulsen failed to connect with Timo Werner's low cross, but after that were irresistible.

Thiago had a simple job in finding an empty net from close range after Lewandowski's shot had struck the post.

Costa struck the upright from an angled strike but the home side would not be denied a second goal for long as Alonso drove home from inside the box after collecting a pass from the scorer of the first.

It was 3-0 and game over before the break as Costa was tripped in the box by Gulasci after running clear of the defence to collect Mats Hummels ball over the top.

Lewandowski converted from the spot and could have had a hat-trick but with just the keeper to beat on two separate occasions in the second half the Polish striker came off second best.

Gulasci was beaten again late in the game but substitute Franck Ribery's fierce strike from inside the box struck the crossbar and bounced on the goal-line before being cleared.
