Well, Bayern got what they needed, but it wasn't easy at all.

They've closed the gap to four points at the Bundesliga's summit, but there's still plenty more work to do.

Thanks for joining us and goodnight.

It's all over at the Allianz Arena in what became an ill-tempered affair.

Bayern close Bayer Leverkusen's lead to four points thanks to Raphael Guerreiro's second half goal.

A free-kick for Union right at the end, a chance to throw everything into the box.

It's getting heated again and this time it's Harry Kane squaring up to Kevin Vogt.

The England captain is booked for the altercation, as is Vogt.

Joshua Kimmich is back on and fine to continue.

Worrying signs for Bayern with Joshua Kimmich down after falling awkwardly on his shoulder.

This is not what Thomas Tuchel would want to see right now.

Five minutes left for Bayern to secure the three points.

Youngster Aleksandar Pavlovic comes on for Konrad Laimer.

So close for Harry Kane's 23rd league goal!

A good cross in and the striker bundles it towards goal, but Frederik Ronnow managed to keep it out.

Leon Goretzka sends a powerful header towards the top corner, but Frederik Ronnow produced a camera save and held on to the ball.

Janik Haberer and Alex Kral come off for Brendon Aaronson and Chris Bedia.

Jamal Musiala and Kingsley Coman make way for Mathys Tel and Thomas Muller.

What has happened here then?

Leroy Sane tries to slap the ball out of Nenad Bjelica's hand and the Union boss didn't take too kindly to it and shoved Sane in the face twice.

A clear red card and a poor moment for the manager.

No penalty is the decision at the Allianz Arena and Bayern are rather fortunate.

It did look like a clip on the heel for Kevin Behrens.

Controversy!

Surely that has to be a penalty for Union as Kevin Behrens is clipped in the box.

The Union players scream for a penalty and I have to say, it does look like one.

The capacity crowd at the Allianz Arena are expecting more goals as Bayern control the game and look to pass the ball a lot quicker than they did in the first half.

You'd think they'll create a chance or two.

A lot more fluidity to Bayern's play after taking the lead. It's like a weight has been lifted off their shoulders.

However, they're pushing for a second because Union are always in the game at just one goal down.

A possible penalty for Bayern is being checked.

Matthijs De Ligt appealed strongly for handball, but it would have been harsh.

VAR says no and play continues.

Bayern look hungry for more goals and so does Harry Kane.

The Bundesliga's leading scorer will know there is a chance here to extend his lead at the top of scoring charts.

Harry Kane will have to wait for his 23rd Bundesliga goal as Leroy Sane was offside in the build-up.

As we were.
