Birmingham City have announced the signing of Kerim Frei from Turkish side Besiktas for an undisclosed fee.
The 23-year-old left-winger has put pen to paper on a three-and-a-half-year deal with the Championship outfit, keeping him at St Andrew's until 2020.
Frei has previous experience in English football with Fulham and Cardiff City, making 23 appearances in the Premier League with the Cottagers before a short stint on loan in South Wales.
Frei went on to join Besiktas for a reported £3m, where he made 83 appearances and scored seven goals.
The five-time Turkish international will wear the number 21 shirt for the Blues and becomes manager Gianfranco Zola's fifth signing of the January transfer window.
