Illness-hit Bayern roar back to floor Ingolstadt

Having scored 20 goals without reply in winning their first five competitive games, including Tuesday's 5-0 Champions League drubbing of Rostov, Bayern leaked their first of the season with just eight minutes gone at Munich's Allianz Arena.

But goals by Robert Lewandowski, Xabi Alonso and Rafinha restored order in the absence of captain Philipp Lahm, defender David Alaba and forward Thomas Mueller to a virus, plus Mats Hummels, who was out with a cold.

"After the drop-outs I had to reorganise the back four," said Bayern coach Carlo Ancelotti.

"It was difficult for us. Sometimes it's not possible to play well, that is when you have to show other qualities, which is what we did."

Ingolstadt took advantage of Bayern's lack of key figures early on.

Australia international Mathew Leckie broke down the left wing and set up Paraguay striker Dario Lezcano, who stroked his shot past Manuel Neuer to silence the 75,000-strong crowd.

The lead lasted just five minutes as Poland's Lewandowski curled his shot past the reach of Ingolstadt's goalkeeper Orjan Nyland for his 11th goal of the season for club and country.

Ingolstadt finished the half stronger, but Bayern were not to be denied a sixth straight win this season.

Alonso belted home his shot into the bottom left-hand corner on 50 minutes, while at the other end, a second top save from Neuer denied Leckie before Rafinha claimed Bayern's late third.

"There aren't many days when you can beat Bayern at the Allianz Arena and this was one of them," said Ingolstadt's captain Marvin Matip, a Cameroon international.

"At the back you could really see the quality of Bayern Munich," he added after Neuer's superb display.

Having hammered six goals past Legia Warsaw in the Champions League on Wednesday, Dortmund rested stars Mario Goetze and Pierre-Emerick Aubameyang -- but still thrashed 10-man Darmstadt 6-0.

Winger Ousmane Dembele's cross was driven home by Gonzalo Castro with just seven minutes played.

The hosts doubled their lead when a long-range shot by new signing Raphael Guerreiro was blocked, but Colombia striker Adrian Ramos tapped home the rebound on 48 minutes.

With their attack in full flow, Dortmund's third goal followed minutes later when USA international midfielder Christian Pulisic, who turns 18 on Sunday, tapped home.

Darmstadt's Peter Niemeyer was dismissed for a second yellow card with 30 minutes left as the floodgates opened.

Castro claimed his second, then Sebastian Rode and fellow new-signing Emre Mor netted.

- RB Leipzig march on -

With his wrist still in a cast after slipping on stairs at home, Javier Hernandez equalised, but then hit the post with a penalty, in Bayer Leverkusen's shock 2-1 defeat to Eintracht Frankfurt.

Mexico international Marco Fabian scored Eintracht's winner after Alex Meier had put the hosts ahead.

Wolfsburg wasted a golden chance to win at Hoffenheim when Julian Draxler's first-half shot hit the crossbar after his Germany team-mate Mario Gomez put him in a great position. The match finished goalless.

Newly promoted RB Leipzig remain unbeaten as they earned a 4-0 win at Hamburg -- Emil Forsberg converted a second-half penalty before Timo Werner netted twice and Davie Selke added a late fourth.

Cologne had briefly gone top of the table on Friday with a 3-0 win at home to Freiburg, while Hertha Berlin hope to match Bayern's record of three wins from three when they host Schalke on Sunday.
