Harry Kane's late penalty ensured Bayern Munich maintained their unbeaten start to the Bundesliga season, but they were held to a surprise 2-2 draw by rock-bottom Mainz at the Allianz Arena.

A share of the spoils meant Bayern dropped points for the first time at home this season, while Mainz earned an unlikely point to move within four of safety.

The goal for Kane was his 50th for Bayern in 2025, making it the first time the England captain hit the half-century mark for club in his illustrious career.

But it looked like it would be a routine afternoon for Bayern when Lennart Karl put them in front after 29 minutes with his third Bundesliga goal of the season.

Mainz only had one win from their opening 13 fixtures coming into the match but stunned the hosts by turning the contest on its head with strikes either side of halftime from Kacper Potulski and Lee Jae-Sung.

Bayern snatched a draw in the 87th minute when Kane converted a penalty for his 80th Bundesliga goal, but they dropped points for just the second time this season.

Bayern had all of the ball in the opening quarter-of-an-hour and Karl put the game's first effort on target straight down the throat of Mainz goalkeeper Daniel Batz.

Mainz almost opened the scoring with their very first attack in the 17th minute when Lee met a cross from the left and his header hit the crossbar.

Kane, fresh from a hat trick against Stuttgart last weekend, then got his head to Michael Olise's cross but saw his effort palmed away magnificently by Batz.

Bayern made their dominance count before the half-hour mark, Kane's ball across falling to Serge Gnabry, who cut it back for Karl, unmarked in the six-yard area, to tap home.

Against the run of play, Mainz got themselves level with the last kick of the half. William Boving's free kick was lifted into Potulski, who nodded it straight into the bottom left corner.

Bayern spurned a big chance to go back in front when Gnabry ran on to Karl's deep cross but was unable to hit the target with his volley.

Instead the basement side took a shock lead with a quarter of the game to play.

Stefan Bell strode out of defence and lofted a ball into the area, where Lee produced a stunning diving header past a helpless Manuel Neuer and into the net.

Bayern committed men forward but were in danger of being undone on the counter, Lennard Maloney almost catching Neuer off his line with an effort from halfway which bounced wide.

Bayern looked set for unexpected defeat until Potulski brought down Kane inside the area and the England captain stepped up to send Batz the wrong way from the spot.
