In a clash that could significantly impact the battle for Bundesliga survival, St Pauli will welcome Union Berlin to Millerntor-Stadion on Sunday.

The hosts were dominant during their match last time out, creating three big chances while facing just one, though it was just their second clean sheet in nine games.

Boss Alexander Blessin can still boast that his side are the league's second-best defensive team having only conceded on 21 occasions, but their return of 14 goals scored is the worst in the division.

In the reverse fixture, St Pauli were beaten 1-0 by Union Berlin on August 30, a closely fought clash in which neither side created a big chance in the second half.

Kiezkickers have been defeated in six of their nine most recent outings - winning the other three - and failed to scored five times in that period.

Blessin's side have only triumphed in one of their eight Bundesliga games at home this term, losing five and drawing two at Millerntor-Stadion.

Union Berlin managed to beat Mainz 05 2-1 on January 19 in a match that saw the victors create four big chances and produce over two xG while facing no big chances in the second 45 minutes.

The victory was head coach Steffen Baumgart's first while in charge of the German club – losing his first two – and it was also just the second time that his side have scored at least two goals in their last 12 matches.

However, Baumgart will still be concerned by his team's defensive record given they have conceded 15 goals in their past seven fixtures.

Union's win against Mainz was their first in their 12 most recent matches, with the club losing eight and drawing three in that time.

The visitors' record on the road is alarming considering they have been beaten in each of their last six games away from home.

Vasilj; Wahl, Sands, Nemeth; Saliakas, Irvine, Boukhalfa, Treu; Guilavogui, Eggestein, Afolayan
