Robert Lewandowski outscored Erling Haaland with a Klassiker hat-trick as Bayern Munich recovered from two goals down to again beat Borussia Dortmund in a 4-2 victory.

Bayern reclaimed top spot in the Bundesliga hours after being knocked off the summit by RB Leipzig, despite an awful start to another epic encounter on Saturday.

The champions were two behind inside nine minutes following Haaland's brace, but Lewandowski had them level by half-time and Dortmund, already missing Jadon Sancho, saw their two-goal talisman hobble off with half an hour to play.

BVB still looked set to hold on and end a run of four league defeats to Bayern, only for Leon Goretzka to break their resolve before Lewandowski's treble-clincher capped another outstanding outing.
