BAYERN GO SIX CLEAR
Another barnstorming performance from Bayern and their talismanic striker Lewandowski. He put them in front before Tolisso's screamer made it 2-0 at half-time. Lewandowski added two more in the second half to complete his hat-trick and bring him to 300 career goals in the German top flight. The visitors go six points clear of Dormtund again thanks to an excellent performance.
Bayern are looking more likely to add to their tally as we approach the final minutes.
That's a whopping 300 Bundesliga career goals for Lewandowski. Former Bayern star Gerd Müller - the Bundesliga's all-time record goalscorer with 365 - is the only other player to have reached that milestone.
Bayern go from back to front again and at the end of the move it's a carbon copy of the third goal. Sane slides the ball to Lewandowski, the Pole tucks it home left-footed. That's 23 league goals for the season now.
HÜBERS HITS THE BAR!
Cologne are doing their best to get what would surely be a consolation goal at this stage. Up from the back for a corner, Hübers crashes a header off the bar.
DOUBLE CHANCE FOR COLOGNE!
Ljubicic sees his dvive beaten away by Neuer, and when the ball is sent back in Modeste can only head the ball over.
NUMBER 22 FOR LEWANDOWSKI!
Leroy Sane makes an instant impact as the Bayern substitute slips in Lewandowski. He slides home left-footed for his 22nd league goal of the season.
Uth heads just wide but it looks like the ball had gone out of play before a cross could be sent into him.
MUSIALA HITS THE WOODWORK!
Jamal Musiala fires the ball towards goal from a tight angle, and it comes off the outside corner of post and bar.
SCHWÄBE SAVES COLOGNE
Lewandowski is sent through by a superb Müller pass, but this time he is driven a little wide and Cologne keeper Schwäbe does well to close him down and make a save.
HECTOR HEADS WIDE
Cologne captain Jonas Hector glances a header wide from a right-wing free-kick.It was a difficult chance.
WE GO AGAIN!
No changes at the break, with a big second half required from Cologne if they are to get anything from this game.
BAYERN IN COMMAND
Bayern are looking good at the break, getting off to a great start when the clinical Lewandowski scored against Cologne for the seventh match running. That first goal came from a one-on-one, and Thomas Müller got his second assist of the match - and 16th of the season - when he set up Tolisso a little further out. The French midfielder got the ball out of his feet and smashed home to give the champions a two-goal lead at half-time. Cologne have struggled to create many chances, but Uth had a goal disallowed and Duda had a great opportunity right before the break.
DUDA MISSES OUT!
After Neuer can only partially clear away a cross, Kainz tees up Ondrej Duda. The Slovak is only about eight yards out when he tries to turn the ball home with his first touch, but his effort drifts wide.
BAYERN ON TOP
The visitors have had 55 percent of the ball so far, with seven attempts on goal to Cologne's two. Bayern have also had five corners to the home side's one.
LEWANDOWSKI FORCES A SAVE
Lewandowski tries his luck from just outside the area, but Schwäbe dives to his right to push it behind.
COLOGNE GOAL DISALLOWED!
Neuer hits a weak clearance to halfway, after which Florian Kainz wriggles into some space. His pass through for Uth is a good one, and the Cologne striker slots the ball home. Unfortunately for the Billy Goats, though, the goal is chalked off for offside after a VAR review.
It could be three. After a spot of head tennis, Müller is six yards out and volleys the ball goalwards on his left foot. Marvin Schwäbe reacts brilliantly to make a sharp save with his left knee.
TOLISSO THUMPS HOME!
What a goal! Bayern break again and the move ends with Tolisso heading the ball to Müller on the right corner of the Cologne area. The German touches it back first time on the volley, and French midfielder Tolisso takes a touch with his right foot before smashing home from the edge of the box with his left. A cracking first goal of the season for the ex-Lyon player.
MODESTE HEADER ON TARGET
Cologne get their first opening of the game, with leading scorer Modeste adjusting to head a cross on target. The French striker might have been coming back from an offside position, but Neuer flung himself to his right just in case.
Germany attacker Müller is finding space and showing some lovely touches. After already setting up the goal, he looks in the mood for more.
Timo Hübers does well to cut out a Gnabry ball across the face of the area and Cologne successfully defend the free-kick that follows. The champions have taken control of the game.
First chance, first goal! Thomas Müller plays in Robert Lewadowski and the Pole has plenty of time to sweep his shot home from inside the area. The flag is up initially but the Bayern striker was onside and the goal is confirmed after a VAR review. That's Lewandowski's 21st strike of this Bundelsiga campaign.
Both sides are feeling each other out at this stage - it looks like it could be a tight enough game.
The game has started in Cologne...
GNABRY'S GREAT RECORD
A MODESTE THREAT?
Cologne ran Bayern close earlier in the season, hitting back from 2-0 down in Munich before eventually losing 3-2 in that Matchday 2 encounter. Serge Gnabry scored twice in that meeting and has a remarkable record against the home side - netting 11 times in eight career games against the Billy Goats. Cologne striker Anthony Modeste was also on target in the reverse fixture, however, and he has 12 Bundesliga goals this season after getting the opener in last week's win at Hertha.
THE LAST TIME THEY MET
Bayern's lead at the top has been cut to three points following Dortmund's win at Freiburg, but Julian Nagelsmann is hoping his side restore a six-point advantage. "It's clear we're the favourites'" he said. "It's also clear we want to win. Our job will be to get a better result than we did against Gladbach."
NEUER AND TOLISSO RETURN
Bayern have made two changes today, boosted by the return of captain Manuel Neuer in goal and France international Corentin Tolisso in midfield. Sven Ulreich and Malik Tillman drop to the bench.
Not surprisingly, the home side have made no changes compared to the team that beat Hertha Berlin 3-1 away last time out.
BAYERN: Neuer (c) - Kimmich, Pavard, Süle, Sabitzer - Roca, Tolisso - Gnabry, Müller, Musiala - Lewandowski. Subs: Ulreich, Upamecano, Richards, Sane, Wanner, Nianzou, Copado, Tillman.
