Defender Malik Tillman was loaned to Scotland's Glasgow Rangers from Bayern Munich for the 2022-23 season.
Rangers says the agreement with Bayern includes a provision allowing it to buy Tillman's rights.
Tillman was born in Germany to a father in the U.S military and a German mother. FIFA approved his change of association from Germany to the United States in May, and Tillman made his U.S. senior national team debut in a June 1 exhibition against Morocco.
Tillman made his Bundesliga debut with Bayern Munich on Dec. 14 and played in six games last season.
