Erling Haaland scored twice as Borussia Dortmund routed Wolfsburg 6-1 on Saturday to maintain their slim chances of winning the Bundesliga.
Dortmund are six points behind Bayern Munich with only a mathematical chance of the title. Six-time European champions Bayern, eliminated in the Champions League this week, can restore their nine-point lead with a win at struggling Arminia Bielefeld on Sunday.
Dortmund took control with three goals in a five-minute spell. Defender Tom Rothe headed home from Julian Brandts corner in the 24th minute, midfielder Axel Witsel pounced two minutes later after Haaland broke free, and defender Manuel Akanji turned in a free-kick from Marco Reus just before the half-hour.
Five minutes later, Emre Can netted with a shot from outside the box that goalkeeper Koen Casteels fumbled.Haaland grabbed his first in the 38th minute when he was set up by Reus and shot past Casteels and the prolific Norway star made it 6-0 in the 54th minute after combining well with Brandt.
Midfielder Ridle Baku got a late consolation goal for Wolfsburg, who had not scored in any of their previous five visits to the Westfalenstadion.
Hungary winger Roland Sallai scored twice as fifth-placed Freiburg beat mid-table Bochum 3-0 to move level on points with fourth-placed Leipzig, who plays on Sunday.
