Chelsea have completed the signing of Mykhailo Mudryk from Shakhtar Donetsk.
The Ukraine international has signed an eight-and-a-half-year deal, with the Blues paying Shakhtar a reported £62million – possibly rising to £88m.
The 22-year-old was in attendance for Chelsea’s game against Crystal Palace at Stamford Bridge on Sunday.
“I’m so happy to sign for Chelsea,” Mudryk told the club’s 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. 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 had looked poised to sign for London rivals Arsenal before a last-minute intervention from recruitment head Paul Winstanley and co-owner Behdad Eghbali on Saturday, with the pair flying to Turkey to negotiate the deal.
He becomes the 14th first-team signing since Todd Boehly bought the club last year, with total spending for his short reign now totalling over £350m.
Portugal international Joao Felix signed on loan from Atletico Madrid for around £9m as the club’s fourth January buy last week, before being sent off on his debut at Fulham on Thursday.
Raheem Sterling, Wesley Fofana and Kalidou Koulibaly have also arrived this season for significant transfer fees as Boehly set about rebuilding Chelsea’s squad.
