Union Berlin substitutes Sven Michel and Kevin Behrens snatched victory from the jaws of defeat against RB Leipzig at the Red Bull Arena.

RB Leipzig 1-2 Union Berlin
Goals: 1-0 Poulsen (46'), 1-1 Michel 86' (assist: Becker), 1-2 Behrens 89' (assist: Michel)

Emil Forsberg was rewarded for his midweek winner from the bench in Leipzig's DFB Cup semi-final against Union with a place in the starting line-up. The Swede was one of six changes made by head coach Domenico Tedesco, resulting in a somewhat disjointed first-half display. Union played their part in upsetting Leipzig's flow with a dogged defensive display that prevented the hosts from registering a single shot on goal. At the other end, Taiwo Awoniyi and Grischa Prömel forced Peter Gulacsi into a pair of routine blocks, while Christopher Trimmel fired against the crossbar with a swerving 20-yard strike on the stroke of half-time.

Leipzig redressed the balance and then some within minutes of the restart by scoring with their first effort on Frederik Ronnow's goal. Christopher Nkunku collected a through-ball from Angelino and sent over a cross that Prömel headed straight out to Poulsen. It was slightly behind the Dane, who had two defenders blocking his view, but that didn't stop him thundering an exquisite first-time finish into the bottom corner. Nordi Mukiele fired against the inside of Ronnow's right-hand post, but two Union subs turned the game on its head. After stooping to level from Becker's near-post cross, Michel back-heeled for Behrens to sweep in a dramatic winner as Union exacted their revenge.
