A moment of uncertainty from goalkeeper Jonas Urbig allowed Benedict Hollerbach to score a late goal as Union Berlin held Bayern Munich to a 1-1 draw at home on Saturday, extending their lead at the top of the Bundesliga to nine points.

Bayern, who are chasing a record-extending 34th league title, climbed to 62 points. Champions Bayer Leverkusen, in second, have a game in hand and travel to VfB Stuttgart on Sunday.

Vincent Kompany's Bayern started brightly and set up camp in the Union half, but the hosts were compact in defence and largely restricted their opponents to long-range efforts.

Serge Gnabry had Bayern's best chance of the goalless first half in stoppage time when Michael Olise played him through on goal, but his shot from a tight angle was saved by goalkeeper Frederik Ronnow.

Bayern continued to probe after the break, with Jamal Musiala and Harry Kane both going close from promising positions, before substitute Leroy Sané finally broke the deadlock in the 75th minute, slotting home Olise's cut-back.

Despite their early dominance, Bayern's lead lasted just eight minutes.

Josip Juranovic floated a cross into the penalty area and Urbig, deputising for the injured Manuel Neuer and Daniel Peretz, could only get a weak shot on target which was headed home by former Bayern academy player Hollerbach.

It was Bayern's second successive league game without a win following last week's shock 3-2 home defeat by VfL Bochum.

For Union, who are now winless in their 12 Bundesliga meetings with Bayern, the draw moved them up one place to 13th. Berlin were without coach Steffen Baumgart, who watched from the stands while serving a touchline ban.
