After Borussia Dortmund moved to the Bundesliga summit with a win in the "Revierderby" , Union Berlin will look to reclaim top spot when they play host to Wolfsburg on Sunday.
Union may have lost their opening two Europa League games, but they are still unbeaten in the Bundesliga this season. They have won four of their six league games, helping them clim to the top of the Bundesliga table after matchday six.
Urs Fischer's side will be a confident mood ahead of Sunday's contest after winning three of their last four league games, including a 1-0 victory over Köln last weekend. A third-minute Timo Hübers' own goal proved to be enough to clinch the three points against Köln, as Union claimed their second clean sheet of the Bundesliga season.
While Union would have been disappointed with a 1-0 Europa League defeat to Braga in midweek, they will turn their focus to Sunday's contest where they have the chance to extend their unbeaten league run to 14 games.
Union have also proven to be a tough team to beat on home turf demonstrated by the fact they are unbeaten in their previous nine home matches in the Bundesliga, while their three home encounters this season have resulted in two wins and a draw.
Kevin Möhwald is expected to miss out for the hosts, while there are also doubts over the availability of Morten Thorsby and Danilho Doekhi.
After collecting just two points from their opening six league games, Wolfsburg finally recorded their first win under Niko Kovač last weekend. Maxence Lacroix headed home in the 60th minute to help his side claim a 1-0 away win over Eintracht Frankfurt. Not only did Lacroix's goal seal three points, but it was also the first time Wolfsburg had scored away from home in the Bundesliga this season.
Despite winning last time out, Wolfsburg will head into Sunday's contest in the relegation zone following Saturday's results. A point would be enough to lift Sunday's visitors out of the bottom three, but they will be aiming to clinch consecutive wins as they bid to move away from the bottom three.
Wolfsburg will look to draw inspiration from their head-to-head record with Union, after losing only one of their six Bundesliga meetings. However, that sole defeat took place the last time the two sides faced each other at the Stadion An der Alten Försterei.
Mattias Svanberg, Jerome Roussillon, Jonas Wind and Patrick Wimmer are all expected to miss out for the visitors due to injury issues, while Kovač has indicated that he will name an unchanged lineup for Sunday's contest.
