Union Berlin host Stuttgart at the Stadion An der Alten Försterei on Saturday in the Bundesliga.Just four points off sixth-placed Bayer Leverkusen, the Iron Ones are looking to remain hot on their coattails in the race for the Europa Conference League play-offs.Despite being winless in three games now, Urs Fischer's men have the momentum as they held reigning champions Bayern Munich in the last game.Marcus Ingvartsen scored in the 85th minute to cancel out Jamal Musiala's opener as the capital side earned an unlikely point at the Allianz Arena.Stuttgart trail Berlin by just a point in ninth and have been a highly attacking outfit, with only four teams in the division scoring more than their 50 goals.At the forefront of this attacking masterclass has been Sasa Kalajdzic, who's struck 14 times in his debut Bundesliga campaign, including nine in the last 10 games alone.He will be the single biggest threat for the hosts, but this will be a tough game for the Austrian, as Berlin have the fourth-best defense in the league.Union Berlin vs Stuttgart Head-To-HeadIn five meetings between the sides, Union Berlin have never beaten Stuttgart, losing once and drawing four times, including each of their last three encounters.🗣️ Urs Fischer on @VfB_int pic.twitter.com/nPHPJFORA3— 1.
