Borussia Dortmund forward Erling Haaland ended his Bundesliga goal drought with a double after teenager Tom Rothe opened the scoring on his league debut as they thumped VfL Wolfsburg 6-1 in a ruthless display at the Signal Iduna Park stadium on Saturday.
Axel Witsel, Manuel Akanji and Emre Can also scored as Marco Rose's second-placed side closed the gap on Bayern Munich before next weekend's Der Klassiker, although the leaders can restore a nine-point advantage at Arminia Bielefeld on Sunday.
Dortmund went ahead in the 24th-minute as 17-year-old Rothe met a corner with a glancing header that crept in, shortly after home goalkeeper Gregor Kobel had produced a brilliant save to deny Wolfsburg's Lukas Nmecha at the other end.
