Borussia Dortmund returned to winning ways in the Bundesliga in convincing fashion with a 6-1 thumping of Cologne.

Dortmund suffered the disappointment of going out of the Champions League to Chelsea and were then held to a draw by struggling Schalke last weekend.

But they were back on form on Saturday evening and led 4-0 inside 40 minutes through Raphael Guerreiro, Sebastien Haller, Marco Reus and Donyell Malen.

Davie Selke pulled one back for the beleaguered visitors before half-time but Haller completed his first brace since recovering from cancer in the 69th minute and Reus added the final goal a minute later.

The victory took Dortmund to the top of the table for one night at least, with Bayern Munich due to face Bayer Leverkusen on Sunday.

RB Leipzig’s miserable week was compounded by a 1-0 loss to Bochum that leaves them eight points adrift of Dortmund.

Four days after they were hit for seven by Manchester City in the Champions League, they were undone by Erhan Masovic’s goal just after half-time, earning a precious three points for strugglers Bochum.

Wolfsburg boosted their top-six hopes with a 1-0 victory over Stuttgart, Omar Marmoush scoring the only goal, while Hoffenheim climbed out of the bottom three thanks to a 3-1 win against fellow strugglers Hertha Berlin, who replaced them.

Andrej Kramaric netted two first-half penalties and Ihlas Bebou scored just after half-time, with Stevan Jovetic managing a late consolation after Mu’nas Dabbur was sent off for Hoffenheim.

Marius Bulter’s injury-time penalty earned Schalke another important point in their fight against relegation in a 1-1 draw with Augsburg, who had Ermedin Demirovic sent off just after Arne Maier had given them the lead early in the second half.
