Polish youngster Krystian Bielik has completed his move from Legia Warsaw to Arsenal for a fee believed to be around £2.5 million.
Arsenal manager Arsene Wenger confirmed last week that the holding midfielder who can also play in the centre-back position was on his way to north London.
The 17-year-old has been likened to Arsenal legend Patrick Vieira and is expected to go straight into the Frenchman’s first-team squad.
