Bonucci goal not enough as Dortmund beat Union

Italian veteran Bonucci put Union ahead from the penalty spot in a dramatic first-half, but Dortmund battled back to claim their fifth win of the season. "We were really good today. I usually like to be critical, but I think we can be really proud of this performance," said Dortmund defender Mats Hummels.

Last season's surprise package Union have now lost their last seven in all competitions as they struggle with the step up to Champions League football in this campaign.

"It is really tough mentally to have to take so many hits. I think the international break will do us good," Union defender Robin Gosens told 'Sky'.

Union's sloppy defending at set-pieces has been a major reason for their miserable run this autumn, and it continued to haunt them in Dortmund. Having started brightly, the visitors allowed Niclas Fuellkrug to give Dortmund the lead at a corner on seven minutes.

Fuellkrug's joy was shortlived, however. Just two minutes later, he deflected a Robin Gosens header into his own net to make it 1-1. The drama continued with three game-changing VAR decisions in the space of 10 minutes.

Union's Alex Kral and Dortmund's Fuellkrug both had headed goals ruled out for offside, before Mats Hummels conceded a penalty with a late challenge on Sheraldo Becker. Bonucci converted with ease from 12 yards to grab his first Bundesliga goal and put Union in front.

Yet Dortmund struck back with two goals in quick succession just after half time. First, former Union player Nico Schlotterbeck whipped a breathtaking shot into the top corner from the edge of the area to level the scores.

Minutes later, substitute Julian Brandt tore through Union on the counter-attack to put Dortmund back in front. The hosts sealed victory through another former Union player on 72 minutes, when Julian Ryerson's long-range shot was deflected in to make it 4-2.
