Bayern Munich 7-0 Union Berlin
Mercifully for Union Berlin, it's all over in Bavaria.
Bayern Munich go top of the Bundesliga in emphatic fashion, in a game full of moments.
Harry Kane's first-half penalty makes the Englishman the fastest man ever to reach 100 Bundesliga goals, but that feat has been outshone by a truly spectacular hat trick from Michael Olise.
A Man of the Match display from the Frenchman, who scores his first ever hat trick for the club as the champions go from strength to strength.
Meanwhile, it's a truly damaging defeat for Union Berlin as their search for a first win will continue into matchday five.
Perhaps most excruciating is the fact they will now need to wait three weeks before they can put this heavy defeat behind them, as the domestic campaign comes to a halt for the extended international break.
Bayern Munich 7-0 Union Berlin
The onslaught continues for the visitors as Bayern continue their relentless pursuit of more goals.
The home side have made a number of substitutions and it's clear that those coming off the bench, see this as an opportunity to get a goal and force their way into the starting eleven.
Union Berlin on the other hand, probably can't wait for the full time whistle to go at this point.
Michael Olise (76 mins)
Olise gets his first Bundesliga hat-trick as he scores Bayern's seventh
WOW! What a way to get your hat trick!
Michael Olise plays a quick one-two with Tom Bischof before bending an incredible shot away from Frederik Ronnow into the top-right corner. Incredible goal!
Michael Olise (73 mins)
Michael Olise gets his second as Bayern hit Union for six
I'm having a hard time keeping up here!
Tom Bischof picks out Michael Olise's run in behind with a lovely ball over the top, before the Frenchman rounds Frederik Ronnow and smashes a right footed shot off the inside of the post and into the back of the net.
Ismael Saibari (70 mins)
Ismael Saibari scores his first Bundesliga goal as Bayern Munich run riot against Union
Bayern Munich have a fifth and it's a five-star goal from Ismael Saibari.
The Moroccan drops a shoulder and skips past two Union defenders to get into the penalty area, before smashing his left-foot strike past Frederik Ronnow.
Bayern Munich 4-0 Union Berlin
Almost a hat trick for Harry Kane.
A long ball over the top finds Jamal Musiala in behind and face to face with an onrushing Frederik Ronnow.
The German looks to go around the goalkeeper but is forced wide and decides to lay it off into the path of Kane, whose first time hit from the edge of the area is blocked by an Union Berlin defender.
Harry Kane (54 mins)
Kane's double makes it four for Bayern Munich against Union Berlin
Clinical from Harry Kane, incredibly cruel for Union Berlin.
The visitors have created two great chances to score in this second half, but Bayern have punished them for not making those chances count.
It's a lovely floated cross over the top from Michael Olise, which Kane flicks past Frederik Ronnow at the near post for his second of the game.
Those early second half glimmers of an Union Berlin fight back have been well and truly snuffed out.
Bayern Munich 3-0 Union Berlin
Image source, Getty ImagesMauro Lustrinelli has made his own half-time substitution, bringing on Tim Skarke for Emmanuel Latte Lath.
Skarke is Union Berlin’s top goalscorer this season, with two goals to his name. The German has yet to start a match this season, coming off the bench now in all four of Union’s matches this season.
His impact off the bench however is undeniable, finding the net in stoppage time on two separate occasions.
Bayern Munich 3-0 Union Berlin
We are back underway for the second half here at the Allianz Arena.

Vincent Kompany makes a substitution before the start of the second half, as Dayot Upamecano is brought off for Kim Min-Jae.
A sensible change from the Bayern boss, with the French defender having picked up a yellow card towards the end of the first half.

Looks like Bayern's new Oktoberfest inspired kit is dividing opinion...

I was watching on my phone for five minutes wondering why Union were all over Bayern.

Incredible Musiala and Olise goals. But 3-0 does rather flatter our performance. Another slow start. First 20 minutes were very dodgy.
Christopher Mackenzie
It would be fascinating to see Bayern vs Barca in a Champions League clash. Two team that relentlessly attack the opposition. If it ever happens, I think it will be a game for the ages.

Bayern Munich 3-0 Union Berlin
Mercifully for Union Berlin, the first half comes to an end.
The home side have played some magnificent football and the visitors just do not know how to deal with that electric Bayern front four.
You'd have to imagine the theme of Mauro Lustrinelli's half-time team talk will revolve heavily around damage limitation.
Bayern Munich 3-0 Union Berlin
Just the two minutes of added time tacked on to the end of the first half here at the Allianz Arena.
Michael Olise (43 mins)
Bayern Munich's Michael Olise makes it three against Union Berlin
Another brilliant strike, this time from Michael Olise.
Jamal Musiala, with his back to goal inside the box, lays the ball back to Olise who whips his effort past Frederik Ronnow's near post and into the back of the net.
This looks like it could be a VERY long night for Union Berlin.
Harry Kane (39 mins)
Harry Kane's 100th Bundesliga goal puts Bayern 2-0 up against Union Berlin
Harry Kane - history maker!
Bayern's talisman makes absolutely no mistake from the spot, sending Frederik Ronnow the wrong way with an emphatic penalty.
That is Kane's 100th Bundesliga goal in only his 98th game.
100 goals in 98 games - Kane makes Bundesliga history
Harry Kane broke the record for the fastest player to reach 100 Bundesliga goals as his double helped Bayern Munich thrash Union Berlin.
A stunning hat-trick from Michael Olise, along with impressive goals from Jamal Musiala and Ismael Saibari, sealed the seven-goal rout as the defending German champions maintained their unbeaten start to the season.
England captain Kane stepped up to score a 39th-minute penalty after Olise was taken down by Tom Rothe in the area, the 33-year-old powering the spot-kick into the corner for his century landmark.
The former Tottenham forward reached the tally in Germany's top tier in 98 games - fewer than any other player in the league's history.
Kane added his second of the night - and 101st Bundesliga goal - when he headed in Olise's superb cross in the 54th minute.
That took his tally to 152 goals in 154 appearances in all competitions since he moved to Bayern in 2023.
Musiala put Bayern - who were wearing special kits to mark Oktoberfest - in front in the 18th minute with a stunning strike from 20 yards after good work from Alphonso Davies down the left.
After Kane's penalty, Olise wrapped his left boot around the ball on the edge of the area and found the net two minutes before the half-time interval.
Saibari made it five, with the summer signing from PSV providing a fine finish in the 70th minute for his first Bayern goal.
Frenchman Olise completed his hat-trick with two goals in three minutes as he first rounded Union Berlin goalkeeper Frederik Ronnow to find the net off the post, before the former Crystal Palace winger struck the goal of the night with another left-footed effort from distance.
'We'll have to wait and see' - Kane on his Ballon d'Or chances
The impressive nature of Kane's speed to 100 Bundesliga goals is shown by the fact the previous record holder needed 30 more appearances to reach the tally.
Dieter Muller's century came in 129 games for Cologne, which is almost the difference of an entire league season.
Bayern legend Gerd Muller is next on the list at 136 games, while ex-Borussia Dortmund forward Lothar Emmerich needed 140 and Uwe Seeler took 157 at Hamburg.
Kane now has seven goals in as many games against Union Berlin, with Stuttgart his favourite opponent with 10 in seven against them.
The England striker scored a remarkable 61 goals in 51 games last season in all competitions for Vincent Kompany's men and has struck six in seven so far this term, highlighting just why he is a major contender for the Ballon d'Or award when it is announced in London on 26 October.
The 200-mark in all competitions is definitely in his sights this term if he reaches the highs of previous campaigns.
Kane's contract is up at the end of this season but, if he signs a new deal, he could be chasing double figures in the Bundesliga.
