The Brazil international has been a key part of a Shakhtar team that has rocked the Champions League this season with strong performances against Chelsea and Juventus.
Willian only has one goal in the league this season, but has come to life in Europe with four in five appearances. Chelsea have had their eye on the attacking midfielder for a while and believe now could be the time for Willian to take the step-up to the Premier League, where he has already expressed a desire to play.
The Brazilian can be used out wide or in the middle and is capable of playing with both feet, often dribbling aggressively and directly with pace.
His skill and speed would make him a great asset in the Premier League but Shakhtar head coach Mircea Lucescu wont let his attacking midfielder leave for anything less than his buyout fee of £28million.
