Cunha, who joined Hertha from Leipzig in the winter transfer window, claimed the visitors' second goal for a 2-1 win at last-place Paderborn on Sunday, four days after Hertha was shocked by Jurgen Klinsmann's abrupt resignation as coach.

Leipzig used set pieces to great effect against Bremen.

Lukas Klostermann opened the scoring in the 18th minute after Patrik Schick helped on a free kick, and Dani Olmo set up Schick for the second goal off a corner in the 39th.

Nordi Mukiele made it 3-0 seconds after the restart to help Leipzig open a two-point lead over Bayern Munich, who can reclaim top spot on Sunday with a win at Cologne.

Hertha spent the days since Klinsmann's announcement trying to avert talk of crisis, and the first win under interim coach Alexander Nouri lifts them nine points above the relegation zone.

Dedryck Boyata put Hertha 1-0 up against the run of play in the 10th minute, eight minutes before Cunha had a goal ruled out through VAR.

Hertha goalkeeper Rune Jarstein deflected an effort from Dennis Srbeny inside his own net early in the second half, but Cunha grabbed the winner in the 67th.

"A huge compliment to the team after all the upheaval," Nouri said.

Karim Bellarabi scored in injury time for Bayer Leverkusen to grab a somewhat fortunate 3-2 win at Union Berlin, where the second half was interrupted due to visiting fans setting off flares.

Wout Weghorst scored a hat-trick for Wolfsburg to win 3-2 at Hoffenheim. The Dutch striker scored two penalties and gave away another.

Freiburg drew at Augsburg 1-1.

Fortuna Dusseldorf are hosting Borussia Monchengladbach in a Rhine derby later on Saturday.
