Bolton Wanderers have completed the signing of Celtic midfielder Filip Twardzik for an undisclosed fee.
The 21-year-old, a Czech Republic youth international, has penned a contract with the Trotters until the end of the 2016-17 season.
Twardzik was handed his Hoops debut in 2012 by current Bolton manager Neil Lennon, back when the Northern Irishman was at the helm of the Parkhead outfit, and made a total of seven appearances for the club.
The youngster began his youth career with spells at German clubs Sachsen Leipzig and Hertha Berlin.
