Borussia Dortmund's under-pressure coach Peter Bosz insisted he will not give up despite seeing his side throw away a four-goal lead in a remarkable Ruhr derby against Schalke.
Goals from Pierre-Emerick Aubameyang, Mario Gotze and Raphael Guerreiro – combined with an own goal from Benjamin Stambouli – had put Bosz's side well in control by the 25th minute of Saturday's Bundesliga encounter at Signal Iduna Park.
But two goals in the space of four minutes hauled Schalke back into proceedings after the break, before Aubameyang's dismissal for a second bookable offence put Dortmund on the back foot.
