Mykhaylo Mudryk is with Shakhtar Donetsk's squad in Turkey.
Mudryk has travelled with Shakhtar to their mid-season training camp as Arsenal seek a breakthrough in talks for the winger, says the London Evening Standard.
Arsenal have had two bids rejected for Mudryk, with the second of those worth around £60million, but they remain in negotiations with Shakhtar.
An agreement has not been found yet, but it is hoped a compromise can be found on Shakhtar's asking price of £85m.
Mudryk has expressed a desire to join Arsenal.
However, with no agreement in place, he travelled with Shakhtar on Tuesday morning to their mid-season training camp in Turkey.
