Josip Juranovic has completed his move from Celtic to Union Berlin.
The 27-year-old right-back has signed for the Bundesliga side for a deal worth a reported fee totalling £10m with £7m up front and £3m of add-ons.
Juranovic joined the Hoops a year and a half ago and helped them win the Premiership title and League Cup last season.
He also starred in the World Cup and helped his Croatia side reach the semi-finals after knocking out Brazil in the quarter-finals.
Celtic, who had prepared for the exit by signing Canada international Alistair Johnston to challenge Anthony Ralston at right-back, confirmed the move on Sunday.
A statement said: “Everyone at the club wishes Josip all the best in his future career.”
