Shakhtar Donetsk have reportedly accepted a €35m (£30m) bid from Anzhi Makhachkala for Brazilian winger Willian.
The 24-year-old has been a long-term target of both Chelsea and Tottenham Hotspur, but Sport Express have now reported that he is on his way to Russia.
Willian has been a key figure in Shakhtar's run to the last 16 of the Champions League this season, as well as their back-to-back triumph in the Ukrainian Premier League.
In total, he has won four league championships, three Ukrainian Cups, three Ukrainian Super Cups and a UEFA Cup since moving from Corinthians for €19m (£16.2m) in 2007.
