Robert Lewandowski scored twice as Bayern Munich inflicted a bruising 4-0 defeat on Borussia Dortmund in interim coach Hansi Flick's first Bundesliga match in charge.
Victorious against Olympiacos in the UEFA Champions League in midweek, Bayern set the tone inside 40 seconds when Dortmund goalkeeper Roman Bürki was forced to race off his line to deny Lewandowski a clear run at goal. Dortmund threatened sporadically coming in off the flanks, but the record champions were relentless as an attacking unit and deservedly went in front in the 17th minute. Serge Gnabry's initial cross was cleared only as far as Benjamin Pavard, whose audacious first-time return pass was dispatched with aplomb by a diving Lewandowski. Former Bayern defender Mats Hummels cleared off the line from Kingsley Coman following another fine piece of Lewandowski play, before Gnabry had an effort ruled out for offside. BVB coach Lucien Favre hooked Jadon Sancho in favour of Raphael Guerreiro with 10 minutes left of a largely one-sided first half, bookended by a shot in anger from Dortmund's Axel Witsel.
If Dortmund were guilty of being far too passive in the first period, they hadn't learned their lesson. The second half was barely two minutes old when Javi Martinez dissected the BVB defence with a raking long ball for Thomas Müller, who burst clear and crossed for Lewandowski. Bayern's No.9 missed his cue, but Gnabry was on hand to stick away the loose ball - the goal standing after a VAR review for a possible offside. Gnabry went within a whisker of applying the finishing touch to a superb run and cross from Alphonso Davies, before Lewandowski curled agonisngly wide with Bayern's next meaningful attack. Dortmund substitute Paco Alcacer spurned a glorious chance to reduce the arrears, and was made to pay as Müller teed up Lewandowski for his second of the match and 16th Bundesliga goal of the season. Hummels inadvertently turned in substitute Ivan Perisic's low cross to compound another chastening loss at the Allianz Arena for last season's Bundesliga runners-up.
- Bayern have won their last six Bundesliga matches at home to Dortmund 2-1, 5-1, 4-1, 5-0, 6-0 and 4-0.
- Lewandowski is the first player in Bundesliga history to score a goal on each of the first 11 matchdays of a season; the first to find the net in 11 successive top-flight matches; and the first to reach 16 goals after 11 match days. He is also the first player to score in successive matches against one team.
- Bayern lined up with the same starting XI in successive matches for the first time this season.
- Gnabry scored his third Bundesliga goal of the season, and eighth in all competitions. He has registered two goals and two assists in his three meetings with Dortmund.
- Müller has provided a team-leading five Bundesliga assists in 2019/20.
