Berlin – While Bayern Munich is confirmed as champion, the relegation battle in the German Bundesliga is heating up. Eight clubs were still trembling before the last four rounds. Already this weekend there are two direct duels in the bottom of the table in the games Wolfsburg against Borussia Mönchengladbach and Heidenheim against St. Pauli – with potentially (preliminary) decisive character. If Heidenheim were to lose against the third-from-bottom team, they would be the first to be relegated.
