Ullrich signed a contract extension with Borussia Monchengladbach until 2029, the club announced. "Lukas is in his third season with us and has developed well. After an initial year of acclimatization, he made his breakthrough as a Bundesliga player last season and regularly demonstrated his great potential in a demanding position. We are convinced and expect him to take the next steps positively as an athlete and as a person, and we are delighted that he also sees his future with us," said sporting director Rouven Schroder.
