Wolfsburg got the best possible start against favourites Leipzig when Christopher Nkunku fouled Kevin Mbabu for a penalty.
But then the worst possible scenario for penalty taker Wout Weghorst.
The ball flying into row Z after he lost his footing.
The dead lock in this German Cup semi-fibnal was brokemn by Leipzig after a determined run by the prolific midfielder Yannick Poulsen.
The Dane with the strength to get past his man – and then a touch of luck with the deflection.
And it was Hee-Chan Hwang who put the tie to bed, when the ball rebounded into his path as Leipzig ran out 2-0 winners.
Searching for their breakthrough season Leipzig are just two points behind Bayern Munbich in the Bundesliga, and just two games away from a first ever German Cup triumph
