Chelsea have completed the signing of Ukrainian winger Mykhailo Mudryk from Shakhtar Donetsk.
Mudryk joins on an eight-and-a-half year deal as Chelsea's fifth senior signing of the January transfer window.
"I’m so happy to sign for Chelsea," Mudryk told the club's official website.
"This is a huge club, in a fantastic league and it is a very attractive project for me at this stage of my career."
Mudryk averages one goal or assist per match this season. He has scored 10 and set up another eight in 18 appearances across league and UEFA Champions League matches.
The 22-year-old has been capped eight times for his country since making his international debut last year.
