Legia Warsaw will make a bumper profit from the sale of Krystian Bielik to Arsenal.

Legia Sport says Arsenal have submitted a bid to sign Bielik - understood to be in the region of £1.6million.

The 16-year-old only joined Legia Warsaw six months ago for a fee of £9,500.

Bielik and his family have reportedly visited London to see the Emirates Stadium and the Gunners' training facilities. They will also watch Arsenal face Queens Park Rangers on Boxing Day.
