Bayern Munich v Union Berlin preview: Bundesliga matchweek 4 at Allianz Arena on Sept 18

Bayern Munich will face 1. FC Union Berlin at the Allianz Arena in matchweek 4 of the Bundesliga 2026-27 season on September 18 (BST), in a fixture previewed ahead of Friday night’s kickoff. Bayern arrive unbeaten in the campaign while Union remain without a league victory.
Bayern, managed by Vincent Kompany, have won four of their last five matches and drawn one, and have featured in three league games this season, failing to score only once. The Bavarians have maintained an attacking style and a high-pressing approach coming into the new campaign, with home advantage expected to be significant.
Union Berlin, led by Mauro Lustrinelli, have not registered a win in the Bundesliga this season and arrive following a 1-3 defeat to FC Schalke. The visitors have conceded seven goals in their last two matches while scoring once, and will travel to the Allianz Arena for this match.
Bayern’s attacking form has been driven in part by Harry Kane, the 33-year-old forward who has produced strong displays in the last two games and registered four goal contributions across those outings. The preview notes Kane’s recent productivity and his role in keeping opposing defences under pressure.
Tim Sharke was Union’s sole goalscorer in their most recent Bundesliga game against FC Schalke after coming off the bench; the 30-year-old recorded the joint-most touches (6) in the opposition box and completed the most dribbles (3) in that match. The report states Sharke will seek an improved contribution to give Union a chance against Bayern.
All members of Bayern’s squad are reported fit and available for selection. For Union Berlin, Marvin Friedrich, Andrik Markgraf, Andrej Ilic, Josip Juranovic, Stanley N’Soki and Oliver Burke are listed as not match fit. The preview provides expected lineups as: Neuer (GK); Stanisic, Upamecano, Kim, Davies; Kimmich, Pavlovic; Olise, Musiala, Diaz; Kane for Bayern, and Ronnow (GK); Trimmel, Querfeld, Uduokhai, Rothe; Aebischer, Kemlein; Sharke, Khedira, Burcu; Latte Lath for Union.
The preview concludes that Bayern Munich are in good touch at the Allianz Arena and projects them to come out on top, offering a prediction of Bayern Munich 3-1 FC Union Berlin. In the United Kingdom the match will be available on Sky Sports, Amazon Prime Video and BBC, and viewers can stream via the Zee5 app and website; the original report also directs readers to follow Khel Now on Facebook, Twitter and Instagram and to use the Khel Now mobile apps and Telegram channel for further updates.
