Robert Lewandowski scored his sixth goal in four Bundesliga games this season as Bayern Munich swept aside hosts RB Leipzig 4-1 on Saturday to go second in the table behind Wolfsburg.

Lewandowski netted a first-half penalty before 18-year-old Jamal Musiala and Leroy Sane added quick-fire goals just after the break in front of 34,000 fans at Leipzig's Red Bull Arena.
