Striker Erling Haaland scored twice as Borussia Dortmund routed Wolfsburg 6-1 on Saturday to maintain its slim chances of winning the German league.
Dortmund is six points behind Bayern Munich with only a mathematical chance of the title. Six-time European champion Bayern, eliminated in the Champions League this week, can restore its nine-point lead with a win at struggling Arminia Bielefeld on Sunday.
There are only four rounds remaining after this weekend.
