Jurgen Klopp's first signing as Liverpool manager, Marko Grujic, can now play for the Reds after being granted a work permit.
The Serbian midfielder signed for Liverpool in January and remained at his former club Red Star Belgrade on loan until the end of last season.
The 20-year-old has played three times for his country and has scored eight goals in 46 career appearances.
Grujic has officially been handed the No.16 shirt at Anfield and can now make his long awaited debut for Liverpool.
