Union Berlin have completed the signing of right-back Josip Juranovic from Celtic in a deal worth up to £10m.
The initial fee is understood to be £7.5m plus add-ons, with the Croatian finalising his switch to the Bundesliga side on Sunday.
The 27-year-old had been a target for Chelsea this January, while Spanish sides Barcelona and Atletico Madrid had also been looking at a move for him.
Celtic had wanted to keep Juranovic in Glasgow and held talks over an improved new contract. However, neither party could reach an agreement before he departed for the World Cup in Qatar.
The former Legia Warsaw defender departs the Scottish Premiership side after joining in August 2021 for a reported £2.5m.
Celtic said in a statement: “The Croatian defender has moved to the German club having won both the league title and the League Cup in his first season with the Hoops and he followed that up by reaching the Qatar World Cup semi-final with his national side where they lost to eventual winners, Argentina.
“Everyone at the club wishes Josip all the best in his future career.”
Juranovic told his new club’s website: “The transfer to Union fulfils my dream of being able to play in one of the best football leagues in the world. The Bundesliga is intense and robust, which suits my game.
“I’m looking forward to playing in front of the fans at the Alte Forsterei soon. In Berlin, I want to improve even more and take the next step in my career.”
Celtic have already announced the signing of Canada right-back Alistair Johnston on a five-year deal.
The Hoops paid an initial fee of £3.5m for the CF Montreal defender, who has already made three appearances for Ange Postecoglou’s side since joining at the start of the month.
Who will be on the move this winter? The January transfer window closes at 11pm in England and at midnight in Scotland on Tuesday January 31, 2023.
