Mario Gomez scored a six-minute hat-trick within nine minutes of coming on as a substitute as Bayern Munich defeated Wolfsburg 6-1 to reach the German Cup final.

In addition to goals from Xherdan Shaqiri, Arjen Robben and Mario Mandzukic - Diego scored Wolfsburg's only goal - Gomez scored his impressive three to keep the German giants on course for a domestic double, having already secured the Bundesliga.
