Arsenal have held productive talks with Legia Warsaw over the midfield prodigy Krystian Bielik and they are poised to complete a deal for him which could be worth up to €3m (£2.4m).

The London club sent representation to Warsaw to meet Legia officials on Tuesday and they put forward their third offer for the 17-year-old. Legia have previously rejected bids worth €1.5m and €2m but Arsenal’s latest offer, which includes add-ons, is believed to have been acceptable.

Bielik, who is 6ft 2in and can also play at centre-half, will join up with Arsenal immediately, rather than returning to Legia on a loan-back arrangement for the remainder of the season.

He joined Legia from Lech Poznan last summer and this has been his debut season at first-team level. Under the manager, Henning Berg, he has made five appearances in the Polish league and one more in the Europa League as a late substitute.

Arsenal invited Bielik to their London Colney training base over the Christmas period and the player also visited Hamburg last week. Roma have shown an interest in him as well. Bielik, who has represented Poland at Under-17 level, has built a big reputation in youth football and he sees Arsenal as the ideal place to develop.
