Bayern Munich's Germany star Mario Goetze came off the bench to score the opening goal in the European champions' comprehensive 3-0 win at his ex-club Borussia Dortmund on Saturday.
.
Goetze, who joined Bayern for €37 million in July after 12 years at Dortmund, gave the perfect reply to the chorus of boos he received at Borussia's Westfalenstadion.
.
The 21-year-old smashed home a Thomas Mueller pass on 66 minutes, before the flood gates opened and Arjen Robben and Mueller added late goals in the final five minutes.
.
"A 3-0 win sounds clear, but they matched us for most of the game, the 1-0 lead we took was decisive," said Robben, who captained the Netherlands for the first time on Tuesday.
.
"They also had their chances. I enjoy duels like this.
.
"How many small boys dream of playing in games like this?"
.
This was a commanding performance and was the first time Bayern have beaten Dortmund in six Bundesliga attempts, dating back to February 2010.
.
Again, Munich ran out winners in a replay of May's Champions League final.
.
Dortmund had been forced to patch together their back four after both centre-back Mats Hummels and left-back Marcel Schmelzer returned from international duty with injury.
.
But there can be no excuses as Bayern extended their record unbeaten run in the Bundesliga to 38 matches to open a seven-point lead over Dortmund, who drop to third.
.
Earlier, Bayer Leverkusen warmed up for Wednesday's Champions League clash at home to Manchester United by going second with a 1-0 win at Hertha Berlin.
.
Striker Stefan Kiessling, who has been repeatedly overlooked by Germany coach Joachim Loew since 2010, hit Leverkusen's first-half winner for his eighth goal in 13 league games.
.
The win came at a cost as Germany winger Sidney Sam is doubtful after suffering a suspected torn thigh just four minutes into the game and will undergo a scan on Sunday.
.
Leverkusen are second in Group A, just one point behind David Moyes' Premier League side.
.
Sixth-placed Schalke, who are away to Steau Bucharest in the Champions League on Tuesday and second in Group E behind Chelsea, drew 3-3 at Eintracht Frankfurt.
.
The Royal Blues flew into a 2-0 lead after only 18 minutes away from home, but leaked three goals in 12 disastrous second-half minutes.
.
Eintracht, who are just above the relegation places, hit the back of the Schalke net four times in those 12 minutes, but one of their efforts was ruled offside.
.
Frankfurt's Spanish midfielder Joselu scored twice with the ex-Real Madrid player adding to his earlier header when he slammed home a long-range shot on 68 minutes.
Borussia Dortmund just had to lose that game. Bayern Munich was just superb!
