Augsburg scored after 30 seconds and again in second-half stoppage time to claim a dramatic 2-2 draw at home to Bayern Munich, as Niklas Sule suffered an injury that will have the Bundesliga champions concerned.

Marco Richter scored in the opening minute for hosts Augsburg on Saturday as Bayern struggled to bounce back from the loss they suffered to Hoffenheim before the international break.

But after the visitors lost a distressed Sule to injury, Serge Gnabry set up Robert Lewandowski to net for a record-equalling eighth straight game at the start of a Bundesliga campaign.

Former Arsenal youngster Gnabry then scored himself in the second half.

That would not prove to be the winner, though, Alfred Finnbogason tapping in one minute into added time to stun Niko Kovac's side.

Had Bayern won, they would have returned to the top of the Bundesliga after Wolfsburg lost at RB Leipzig. Instead, Bayern were left a point off the pace, with Borussia Monchengladbach in with a chance to extend their lead when they played Borussia Dortmund later on Saturday.

An explosive start saw Augsburg forward Richter volley in from eight yards after Rani Khedira headed into his path, capping a move that began with a simple throw-in.

Richter flashed a shot wide from a great chance to add a second goal, with Sule injured in the build-up when challenging Florian Niederlechner for possession.

The Bayern defender immediately clutched his leg and David Alaba replaced him.

But Bayern levelled in the 14th minute, as Lewandowski headed in Gnabry's in-swinging cross, keeper Tomas Koubek unable to keep it out despite getting a hand on the ball.

Bayern came within inches of taking the lead twice before half-time, with a Gnabry volley bouncing off the post and Tin Jedvaj clearing Thiago Alcantara's effort off the line.

Four minutes into the second half, though, Bayern did break through as Gnabry cut inside and found the bottom corner with a sweet left-footed strike from 20 yards after being found by Philippe Coutinho.

Koubek made what proved to be pivotal saves from Coutinho and Kingsley Coman, while substitute Thomas Muller could not convert a glorious late chance just before Augsburg went up the other end to level.

Two substitutes combined as Sergio Cordova outmuscled Lucas Hernandez and laid it on a plate for Finnbogason. The draw left Kovac dismayed and home boss Martin Schmidt celebrating in delight after a contest that matched last year's encounter – which Bayern won 3-2 after also conceding in the first minute – for drama.

What does it mean? Sule blow adds to Bayern woe

It was a costly day for Bayern with Sule going off injured in the 12th minute. The blow could prove more serious than the loss of two points in the title race, against an Augsburg team who are in dire form with only one win in 13 matches .With Mats Hummels gone and Jerome Boateng out of favour, Sule, 24, has impressed in becoming first choice for club and country but now looks set to miss out during a key period of the season.

Power Serge electrifies Bayern

Gnabry set up Lewandowski's goal and then scored a sublime one himself which would have reminded Bayern fans of Arjen Robben. He created four chances for his team-mates and hammered in six shots on goal in a terrific performance.

Late Hernandez error proves costly

Hernandez was recently the subject of a fitness row between Bayern and France, but he did not show what the fuss was all about as he weakly went down under pressure from Cordova in the build-up to Augsburg's equaliser.

Key Opta stats

- Lewandowski’s feat of scoring in each of the first eight Bundesliga matchdays equals the record set by Pierre-Emerick Aubameyang - then of Borussia Dortmund - in 2015/16.

- Augsburg have conceded 21 goals across the first eight matchdays – more than ever before in their Bundesliga history at this stage.

- Bayern have only kept three clean sheets in 12 competitive games this season: twice at home (3-0 v Red Star Belgrade and 4-0 v Cologne) and only once away (3-0 at Schalke).

- Bayern have collected 15 points from the first eight Bundesliga games, their worst record since 2010-11 (11 points back then) – a season when Dortmund took the title.

- Bayern have conceded two goals in each of their last four matches in all competitions. The last time they had such a run was back in November/December 2004.

What's next?

Bayern will look for a first win in three when they are away to Olympiacos in the Champions League on Tuesday, before hosting Union Berlin in Bundesliga business on Saturday. It does not get too much easier for Augsburg, who are away to Wolfsburg next Sunday.
