RB Leipzig midfielder Xaver Schlager, 28, is a potential target for Celtic as his contract is due to expire this summer. Despite his contract situation, he has made 13 appearances and scored 2 goals in the Bundesliga for the German club this season.
RB Leipzig's interest in Arne Engels could create an opportunity for Celtic to inquire about the Austrian international, who has 49 caps and 4 goals for his country and is capable of playing in various central midfield roles. He has also been linked with Roma and Juventus. In January 2026, reports indicated RB Leipzig would ask for a fee of €4-5 million for a winter transfer. Transfermarkt estimates his current market value at €10 million. His most recent completed transfer was from VfL Wolfsburg to RB Leipzig in July 2022 for a reported fee of €12 million.
