Borussia Dortmund denied RB Leipzig top spot in the Bundesliga as Erling Haaland reignited his team's title ambitions with two goals in a 3-1 win at the Red Bull Arena.
Bayern Munich's dramatic collapse against Borussia Monchengladbach on Saturday (AEDT) left them vulnerable at the summit, only for bitter rivals Dortmund to do them a favour.
After a cagey first half, Haaland stole the show, helping to create Jadon Sancho's opener before heading home the England winger's cross.
Haaland dispatched his 19th goal of the season across all competitions six minutes from time, though Alexander Sorloth beat Roman Burki at the second attempt to register a consolation for Leipzig, who remain two points behind Bayern after their nine-match unbeaten run in the Bundesliga came to a halt.
The most notable moment of a forgettable first-half came when Axel Witsel crumpled to the turf with a nasty-looking ankle injury and had to be replaced by Emre Can
Dortmund found fresh intent after the restart, with Sancho sliding in Marco Reus to draw Peter Gulacsi into a sharp save at his near post.
Can headed over from the resulting corner but Dortmund would not rue the miss for too long.
Haaland raided down the Leipzig left and Reus cleverly flicked his cross into Sancho's path for an assured finish.
Dortmund's number nine took up a more familiar position in the 65th minute, collecting Sancho's through-ball and thumping a left-footed shot that Gulacsi tipped against the crossbar.
It was Leipzig's turn to test out the furniture shortly afterwards as Dani Olmo drilled across Burki and against the base of the left post, yet Dortmund doubled their lead when Haaland danced through three challenges and was on hand to head in Sancho's curling cross.
BVB’s third was similarly picturesque – Reus unlocking the Leipzig offside trap and Haaland coolly rounding Gulacsi to tap into an empty net.
Burki seemed to have done enough to deny Sorloth a consolation, but the Leipzig striker latched onto the rebound to slam in a maiden Bundesliga goal.
