Borussia Dortmund kept the heat on Bundesliga leaders Bayern Munich ahead of Der Klassiker with a 2-0 win at 10-man Wolfsburg on Saturday.
A sixth straight league victory for Dortmund was not nearly as impressive as last weekend's crushing of rivals Schalke but again moved Lucien Favre's challengers to within a point of Bayern prior to the late kick-off between the defending champions and Eintracht Frankfurt.
Raphael Guerreiro struck twice in the Revierderby and was on target once more, breaking the deadlock with his eighth Bundesliga goal of the season – his best return in a single league campaign.
