That's all from me, goodbye!
Hoffenheim move top of the Bundesliga with that brilliant winning performance and face an away trip to Eintracht Frankfurt next Saturday. Meanwhile, Hansi Flick's Bayern side turn their attention to another trophy up for grabs in the German Super Cup on Wednesday against Borussia Dortmund.
A remarkable win for Hoffenheim who fully deserved the result from their performance. Bayern offered little in attack and were shaky at the back. A reality check for the champions who were poor all across the pitch today and beaten by an energetic and clinical side in Hoffenheim. Goals from Bacakcic, Dabbur and two from in-form striker Kramaric sealed the win after Kimmich's curled strike just before half-time turned out to be a small consolation for Bayern.
90' + 4' FULL-TIME: Hoffenheim 4-1 Bayern Munich
90' + 3' CLOSE! Muller drifts into the box and his shot rolls wide of the post and sums up Bayern's performance.
90' PENALTY! Bebou beats three players on his own and nicks the ball past Neuer before being taken down for a penalty!
89' The fans inside the Prezero Stadium are making a racket as we enter the final minutes.
88' MISS! Kramaric is played through by Bebou but he can't seal the win in style as his shot flies over the bar.
87' Kimmich whips the ball into the box but Baumann comes to collect the ball confidently.
85' Just over five minutes left in this game and Bayern are still struggling to find any openings for an attempt on goal.
82' Hoffenheim thoroughly deserved to be 3-1 up in this game. Bayern have offered nothing since the break and have been naive in defence.
75' BIG SAVE! Neuer saves with his foot after Skov found himself in acres of space and drilled a shot hard and low but the big German 'keeper saves well.
74' Lewandowski goes for the spectacular with an overhead kick but the offside flag is up.
70' Bayern are increasing the pressure on the hosts now with continuous crosses into the box and not letting Hoffenheim out.
68' Posch does brilliantly to intercept a dangerous cross as the Bayern attack was lining up for an equaliser.
65' Hoffenheim are still looking for a third goal with the Bayern defence looking a bit shaky still.
62' Sane stretches to reach a cross from Muller but the former Manchester City man can't direct the ball goalbound.
57' Kimmich has moved over to right back with Goretzka and Tolisso now pairing in midfield.
55' CROSSBAR! Zirkzee drills a shot from close range at Baumann and it flicks up onto the crossbar!
54' Bayern are preparing a double change with Lewandowski and Goretzka preparing to come on.
52' A well-worked move from Bayern ends with Sane's shot being deflected into the hands of Baumann.
50' ALMOST! Dabbur sneaks in behind Alaba and volleys an effort at goal but Neuer saves well.
49' Tolisso is fouled off the ball by Geiger and Bayern regain possession.
47' Sane delivers a cross to the back post but no one in red can get to the ball and it goes out for a goal kick.
46' The second half is underway!
As it stands, Bayern's 32 game unbeaten streak will come to an end unless they turn this game around in the second half. Hansi Flick will be hoping for a much better showing after the break, especially from Zirkzee who has struggled to get into the game at all.
Hoffenheim lead at the break 2-1 after goals from Bicakcic and Dabbur gave the hosts a shock two nil lead before Kimmich pulled a goal back for the champions who have struggled to break down a stubborn Hoffenheim defence.
45' + 4' HALF-TIME: Hoffenheim 2-1 Bayern Munich

34' UNLUCKY! Sane flashes a header just wide of the post as Bayern continue to push for a way back into this game.

32' Gnabry tries to play through Muller but his pass is poor and the ball rolls out for a Hoffenheim goal kick.
