Arsenal defender Krystian Bielik is closing in on a move to Derby County.
The Rams are in advanced talks with the 21-year-old over a deal to take him to the Championship club, which could eventually be worth around £10million.
Bielik has been with Arsenal since 2015 after they paid Legia Warsaw £2.4m to sign him.
The Poland Under-21 international has been sent out on loan repeatedly since then, with his most recent spell being at Charlton Athletic last season.
As Standard Sport reported earlier this month, Bielik had been told he would not be part of Unai Emery’s plans this season.

That sparked interest from a host of clubs, including AC Milan, but Derby are set to win the race for the defender.
The Rams are in advanced talks with Bielik, who can also play in midfield, as part of a move that could eventually set them back £10m if various clauses are met.
The money could be a welcome boost for Arsenal, who themselves are looking to do more business before the transfer window shuts.
The Gunners remain interested in Celtic defender Kieran Tierney and are expected to make a new offer.
However, the money from Bielik’s departure could also help fund the purchase of a new centre-back.
Club captain Laurent Koscielny’s future remains uncertain as he tries to force through a move to France.
The 33-year-old’s departure would leave Arsenal light in the heart of defence and the money from Bielik’s sale could help fund a replacement.
