We're into four minutes of added time here in Leverkusen.
FIRST GOAL EVER FOR WIRTZ
A bittersweet moment for Wirtz as he scores his first-ever professional goal at just 17 and what a goal it is. He's in the box and cuts onto his left foot past Hernandez with a moment of space to shoot, and he curls the ball high over Neuer and into the far top corner.
ON THE HOME STRETCH
Bayern cruising towards all three points now which will take them nine points clear of second-placed RB Leipzig. Dortmund play this evening, and a win for them over Hertha Berlin would take them within seven points of the league leaders with four games to play.
RECORD FOR LEWY
Bayern's star No.9 has now scored 44 goals in 38 competitive games this season - a new personal record for Lewandowski from a single season.
DIABY WORKING HARD
Again it's the winger causing problems as his pace gets him in behind Pavard down the left. He has Volland calling for the ball at the back post, but he goes to chip Neuer instead, with the Bayern 'keeper able to tip the ball over his own crossbar.
Another player making his comeback now is Kevin Volland. Returning from injury to play for the first time since the league's restart.
After a few weeks on the sidelines, the Spanish playmaker is back on pitch for Bayern and makes his 150th Bundesliga appearance in the process.
BAYERN IN CONTROL
With that game, some burst of life has gone out of the Leverkusen side and Bayern are remaining composed. Keeping control of the ball and staying patient when the home side have it themselves. It's been another measured performance since they went behind in the 10th minute.
LEWANDOWSKI MAKES IT FOUR!
It's the 30th goal of the season for Lewandowski and the 20th assist of the season for Müller. A simple cross from the right corner of the Leverkusen box and it's perfect for the Pole to power beyond Hradecky with a header. That may well be game, set and match here in Leverkusen.
GNABRY SO CLOSE
Coman works his magic down the left as he cuts inside and out of Dragovic before clipping the ball to the edge of the box. Gnabry is on hand to meet the ball, but sends his shot narrowly wide of the Leverkusen goal. A huge chance to ice this game.
NOT ENOUGH FROM DIABY
Fantastic initial work from the Frenchman to skip past his fellow countryman Pavard. He's still 30 yards from goal with time to pick his next step, but irrationally lashes a shot goalward which goes well wide of the Bayern goal. Leverkusen can't afford to waste many more of these half-chances.
While Bayern have offered little going forward themselves in this second half so far, they have kept Leverkusen from piling on the pressure too much at the other end themselves. It's been an even game since the second period began. The next goal will be crucial.
The Bayern midfielder is hurt under a challenge from Wirtz, but should be able to shake it off.
BAYER STARTING WELL
The home side have started this second half well and have been keeping the pressure on the Bayern goal. Alario goes close with a header at the back post which is deflected behind. A goal now would bring the game alive once again.
TAPSOBA STOPS COMAN
The Frenchman is bearing down on the Leverkusen goal at speed, but is caught-up by Tapsoba and his challenge is timed perfectly to knock the ball back to Hradecky.
WIRTZ VS. DAVIES
What is sure to be a head-to-head battle worth keeping your eye on in this second half is Florian Wirtz vs. Alphonso Davies on the far side. The 17-year-old against the 19-year-old, two future stars of the game facing each other for the first time. A good test for Wirtz in only his fourth league appearance.
DIABY TAKES HIS TIME
And too much time in the end. He's played in behind by Wendell and waits to shoot, but in the end, sees his effort blocked behind by the challenge of Boateng chasing back. His blushes are also saved by the offside flag being raised on the far side.
BAYERN RUNNING HARDER
A key stat to keep an eye on in the second half is that Bayern registered 30 more sprints than their hosts in the opening period. Let's see if Leverkusen can get their legs moving more after the break.
SECOND HALF UNDERWAY
We're back for the second half and the home side have made three changes during the break. Wendell, Demirbay and 17-year-old Wirtz are all on.
GNABRY MAKES IT THREE
And just like that, it's three for Bayern. Kimmich sends a long ball from defence over the Leverkusen backline and Gnabray latches onto it before lobbing the ball over Hradecky for his 12th goal of the season.
HUGE CHANCE FOR A THIRD
Leverkusen's defence is all at sea here as Gnabry is played clean through on goal. He has all the time in the world to pick his spot as he closes on goal from the right, but Hradecky makes a big save at his near post.
A COUNTERING SPECIAL
Bayern break from their own box and stay composed in possession as they move the ball forward. Coman cuts the ball inside to Müller who then flicks the ball onto Goretzka before he slots his shot past Hradecky - who got a hand to it but couldn't keep it out - to turn the game around.
A caution for Müller now means both he and Lewandowski will miss the Gladbach game next week.
LEWANDOWSKI SNATCHES AT ONE
Fantastic long ball from Alaba as he spots Lewandowski breaking from his marker into the Leverkusen box. He chests down and shoots at goal, but drags his effort wide across the face of Hradecky's goalposts.
DIABY FORCES A SAVE
Good work from Leverkusen to work the ball to the edge of the Bayern box. Amiri cuts in from the right flank and finds Diaby on the edge of the penalty area. The Frenchman works the ball onto his right foot to shoot, but it's a simple one for Neuer to handle.
The winger is the fourth player to be cautioned in this first half, he too fouling Davies.
The away side have had seven attempts on goal compared to Leverkusen's one, with almost 60 per cent of the possession now in this first half as well. The scoreline remains level though as he close in on half-time.
He's cautioned for a foul on Sven Bender and is now suspended for Bayern's home game vs. Gladbach next week.
The wing-back is struggling to contain Davies on the near side and he's cautioned for a foul on the Canadian.
The Frenchman does the job to bring Bayern level and it all comes from fine work from Leon Goretzka. He steps up in midfield and nabs the ball back from Moussa Diaby before slotting Coman in behind the high-line of Leverkusen's defence. He's all alone and calmly slots the ball past Hradecky into the far bottom corner.
COMPACT IN ATTACK
Bayern are allowing Davies and Pavard to do a lot of the work on the wings so far. Both Coman and Gnabry are moving inside to join Lewandowski and Müller and attack from more central positions. So far, to no joy.
The offside flag saves Bayern's blushes as they fail to put the ball past Hradecky. Müller's dink over the top is latched onto by Lewandowski in the box but he's forced to produce a Bundesliga logo style stretch to control it. Coman then shoots after his touch, Hradecky saves and Lewandowski's rebound is also saved on the line, but the Frenchman is ruled to have been offside after the Poland striker's first touch.
WING-BACKS ON SHOW
While it's a three-man defence when Leverkusen have possession, Leon Bailey and Nadiem Amiri have sat in as wing-backs for the most part in these opening 20 minutes or so. As you can see checking the average line-ups so far, both Bailey and Amiri are almost level with the defensive line.
25 UP FOR ALARIO
His opener today was Alario's 25th Bundesliga goal in 72 appearances. It also came with the game's first shot at goal from either side.
This is the earliest goal Bayern have conceding in the Bundesliga since Leon Bailey opened the scoring at the Allianz Arena in the reverse fixture. He also found the net in the 10th minute on that day.
ALARIO OPENS THE SCORING
Bailey's throw-in is touched down by Boateng towards Baumgartlinger, who flicks the ball over him and the Bayern defence for Alario to chase down the left. He beats the offside trap and races into the box before sliding the ball under Manuel Neuer with an ice-cold finish.
The Frenchman is cautioned for a dive.
USING THE SPACE
Both sides are making the most of the width of the BayArena pitch here. Leverkusen are starting slightly deeper in their own half, trying to battle against Bayern's dominance in the opening minutes. Compact in the middle from the home side defensively.
Bayern trying to find their flow early here on the ball. High pressing making life difficult for the home side, as we have come accustomed to seeing from the league leaders in recent months.
HAVERTZ IN THE STANDS
The missing man for the home side today is in the stands watching on.
AWAY WE GO!
The ball is rolling in Leverkusen. Let the fun begin!
READY TO ROCK
It's going to be a fun one here in the sunshine at the BayArena. Leverkusen hosting Bayern on this Saturday afternoon. Get ready to enjoy the game as it happens with our live updates from the first kick to the last.
BAILEY TO WORK HIS MAGIC AGAIN?
Only two teams have beaten Bayern under Hansi Flick this season: Borussia Mönchengladbach and Leverkusen. With Bayer at home today, that obviously means they took all three points from their trip to the Allianz Arena earlier in the year. Leon Bailey was the hero that day, scoring a brace either side of a Thomas Müller goal in the first half to earn his side the win. He starts again today, with the same result in mind.
BIG THINGS AT STAKE
While Bayern are closing in on an eighth consecutive title which could be sealed next week if results go their way, Leverkusen are in a fight for the final Champions League places for next season. Four points currently separate Leverkusen in fifth and Dortmund in second, with a win today doing them a world of good, especially after Gladbach's defeat to Freiburg last night.
GOALS ON THE WAY?
Both these sides have gone goal crazy in the Bundesliga this season, and especially the league leaders. Bayern have scored 86 goals this term - a Bundesliga record after 29 rounds of fixtures. Leverkusen have 54, the fifth-most this season and even without Havertz could still cause problems to Bayern today with their attacking line-up.
BAYERN'S BOGEY TEAM
Leverkusen have won their last two Bundesliga encounters with Bayern. They have never won three in a row against the record champions. The home side have won two and lost just one of their last six matches on home soil against the record champions: the 3-1 reverse on 12 January 2018. Bayern have failed to score on four of their last eight visits to the BayArena.
MISSING KAI HAVERTZ
This really could be a huge blow for Leverkusen. Only Lewandowski has scored more goals in 2020 than Havertz in the Bundesliga, but the home side's star is out today. The job will be replacing both his goal and his influence in the game. Havertz is Leverkusen’s top scorer with 11, five of which have come in the four matches since the season restart. His strike at Freiburg on Matchday 29 took him to 35 Bundesliga goals making the Leverkusen prodigy the first-ever to reach the milestone before his 21st birthday.
LEVERKUSEN TEAM NEWS
The big, big news from Peter Bosz's team is that Kai Havertz is out. The Leverkusen coach had said he was ready for this game but the 20-year-old suffered a setback during training in midweek and is therefore unfit for this game. Still, it's an extremely attack-minded team. With Nadiem Amiri, Leon Bailey, Karim Bellarabi and Moussa Diaby all starting, while Lucas Alario comes in for Havertz.
BAYERN TEAM NEWS
Just one change from Hansi Flick's side which beat Fortuna Düsseldorf last weekend as Jerome Boateng returns to the starting line-up ahead of Lucas Hernandez. Thiago is fit to start from the bench but does not displace Leon Goretzka in midfield.
LEVERKUSEN STARTING XI!
Hradecky - Tapsoba, S. Bender, Dragovic - Amiri, Aranguiz, Baumgartlinger, Bailey - Bellarabi, Alario, Diaby
Özcan, Tah, Paulinho, Demirbay, Wendell, Weiser, Palacios, Wirtz, Volland
