Robert Lewandowski claimed his 15th goal this season in all competitions as Bundesliga leaders Bayern Munich came from behind to claim a 3-1 win at Stuttgart on Saturday.
Stuttgart striker Tanguy Coulibaly, 19, fired the hosts into a shock early lead after a cross caught Bayern center-backs David Alaba and Jerome Boateng napping.
However, Kingsley Coman equalised with a superb low finish before Lewandowski drilled home from 20 metres to put Bayern 2-1 up at the break.
Brazil winger Douglas Costa, a second-half replacement for Coman, grabbed Bayern’s third goal late on to seal a win which leaves the holders two points clear of RB Leipzig.

Reyna, 18, set up Hazard to pull a goal back, but it was too little, too late.

Just 60 seconds after coming off the bench, forward Christopher Nkunku netted Leipzig’s second goal early in the second half.
