Leeds United confirm the signing of 17-year-old Mateusz Bogusz from Ruch Chorzow, subject to international clearance.
The Polish midfielder has signed a two-and-a-half year deal at Elland Road, running until the summer of 2021.
Bogusz becomes the club’s second signing of the January transfer window, following the arrival of Kiko Casilla from Real Madrid.
He has scored six times in 34 appearances for Ruch who are in II liga and he has also won international caps at youth level for Poland.
The midfielder will initially link up with Carlos Corberan’s Under-23 side.
