Robert Lewandowski scored twice, including a second-half penalty, to guide the German champions Bayern Munich to a crucial 3-2 victory at title rivals Borussia Dortmund on Saturday and a four-point lead at the top of the Bundesliga.

The Pole opened his account in the ninth minute to level after Dortmund had taken an early lead through Julian Brandt, and then converted a controversial 77th-minute spot-kick to seal victory with his 16th goal of the campaign.

In Series A, AS Roma collapsed to a 3-0 defeat at home to manager Jose Mourinho’s former club Inter Milan on Saturday as the champions climbed to second in Serie A and inflicted a fourth defeat in six league games on the capital club.

Mourinho led Inter to an unprecedented treble in 2010 but his first meeting with them as an opposing coach ended with the second Serie A home defeat of his career in his 46th match — the other coming against AC Milan in October.

The Portuguese pointed to his side’s absentees, who included the suspended Tammy Abraham and Rick Karsdorp and injured captain Lorenzo Pellegrini, after a comprehensive defeat.

“Inter are stronger than us in normal circumstances, in these circumstances, they are much stronger,” Mourinho told DAZN.
