Chelsea have completed the signing of Ukraine forward Mykhailo Mudryk from Shakhtar Donetsk.
The 22-year old arrives at Stamford Bridge on an eight-and-a-half year deal for a fee of 70m euros (£62m), plus a further 30m euros (£27m) in bonuses.
Chelsea beat Premier League rivals Arsenal to the signing of Mudryk, who scored seven goals in 12 league appearances for Shakhtar this season.
“I’m so happy to sign for Chelsea,” said Mudryk.
“This is a huge club, in a fantastic league and it is a very attractive project for me at this stage of my career. I’m excited to meet my new team-mates and I’m looking forward to working and learning under Graham Potter and his staff.”
Mudryk is at Stamford Bridge for Chelsea’s Premier League fixture against Crystal Palace on Sunday afternoon.
He had looked set to sign for Arsenal, but Shakhtar confirmed club president Rinat Akhmetov met with Chelsea co-owner Behdad Eghbali on Saturday to discuss the player’s move to west London.
“I am convinced Mykhailo will win the respect, sympathy and love of all connoisseurs of world football with his speed, his technique, his bright and beautiful game,” said Akhmetov.
