Arminia Bielefeld host Union Berlin on Sunday in a crunch Bundesliga clash for the hosts, who are embroiled in a relegation battle.Mainz's draw with Schalke on Friday night pushed Arminia to 17th spot in the Bundesliga. Should they finish there at the end of the season, they would be automatically relegated.Arminia are level on points with Mainz and Hertha Berlin, but are the worst-placed out of the three at the moment due to their goal difference.They do, however, have a game in hand to play this coming midweek. Their fixture against Werder Bremen last month was postponed and will be played on Wednesday evening.In their last match, Arminia were beaten 3-0 by Borussia Dortmund. They managed to keep Dortmund goalless until halftime, but strikes from Mahmoud Dahoud, Jadon Sancho and Reinier secured the win for Dortmund.Final.#BVBDSC | 3:0 pic.twitter.com/50D9xLshhd— Arminia International (@arminia_int) February 27, 2021Meanwhile, Union have not lost any of their last three games in the league, picking up five points from those encounters.In their last match, they drew 1-1 against Hoffenheim, with both goals coming in the first half.
