Bayern Munich, who also dropped points in a surprise loss at home to Bochum last week, could be just six points ahead if Leverkusen win at Stuttgart on Sunday.

Bayern had most of the ball but struggled to break through a resolute Union defence.

With few chances in the opening period, Bayern's best chance came after 51 minutes when Harry Kane drilled a free-kick through the wall but into the palms of Frederik Ronnow.

Leroy Sane put the visitors ahead after 75 minutes when he skated through a crowded penalty area to tap in a Josip Stanisic pass.

Union were however the better team after the goal and the hosts levelled through Benedict Hollerbach, who was on the spot to take advantage of an error from rookie goalkeeper Jonas Urbig.

Union rose in intensity in the dying stages but were unable to land the killer blow which would have seen them beat Bayern for the first time in their history, on their 12th attempt.

Despite hovering dangerously close to the relegation spots for much of the season, Union have a strong record at home against the league's best sides.

Borussia Dortmund, RB Leipzig, Eintracht Frankfurt, Mainz, Freiburg and now Bayern have all left Berlin without winning.

Unlikely Champions League candidates Mainz and Freiburg drew 2-2 draw. Hosts Mainz, reduced to 10 men when Dominik Kohr saw red after 43 minutes, twice took the lead but Freiburg equalised both times.

The result leaves Mainz third and Freiburg fifth, with neither side having ever played in the Champions League.

An Alassane Plea hat-trick took Borussia Moenchengladbach to a 4-2 win at Werder Bremen, keeping the visitors on track for a return to European football.

Plea's first-half brace had Gladbach on track but Bremen scored twice in seven minutes through Romano Schmid and Andre Silva, his first for the club, to level things up at half-time.

Plea scored just two minutes into the second half and Germany striker Tim Kleindienst added another to seal the victory.

Augsburg's impressive 2025 continued with a 1-0 home win over Wolfsburg, with Phillip Tietz scoring the only goal.

Augsburg are now unbeaten in 10 in the league and have conceded just three goals this calendar year, the lowest mark in the top five European leagues.

In Saturday's late game, RB Leipzig host Dortmund in a must-win game for either side's hopes of reaching next season's Champions League.
