Bayern Munich 5-1 Borussia Dortmund: Thomas Muller and Robert Lewandowski both score twice as Bavarians run riot in Der Klassiker and extend lead at top of Bundesliga

Bayern Munich's steam-rolling lead at the top of the Bundesliga shows no signs of letting up as Pep Guardiola's side cruised to a 5-1 victory over rivals Borussia Dortmund in Der Klassiker.

Bayern's eighth win in as many games, courtesy of two goals each from Thomas Muller and Robert Lewandowski as well as a further strike from Mario Gotze, sees them open up seven-point lead at the table's summit.

Germany international Muller opened his account in the 26th minute and doubled the hosts' lead with a penalty nine minutes later for his eighth league goal this term.

Pierre-Emerick Aubameyang kept up his remarkable run of scoring in every one of Dortmund's league matches this season as he slotted in from close range a minute later.

But Bayern forward Lewandowski killed off any hopes of a comeback with two goals early in the second-half to take his tally to 12 goals in all competitions in the last 12 days alone and nine in his last three Bundesliga matches, a league record.

His 12 league goals on the first eight match-days also equalled the Bundesliga record set by Christian Mueller in 1964-65 and Gerd Mueller in 1968-69 seasons.

Former Dortmund team-mate Gotze added a fifth goal for the dazzling Bavarians in the 66th with the visitors having unconditionally surrendered.
