Shakhtar Donetsk sporting director Darijo Srna has again declared Mykhaylo Mudryk will only leave for huge money.
The Ukraine international is a target for Arsenal, Everton and Newcastle United, among several big spending clubs across Europe.
Srna declared: "If he had a Brazilian passport, he would be worth €100m.
"If someone wants him, they will have to pay a lot of money.
"Mudryk is better than any Brazilian who has ever played for us. That's no exaggeration. Football has been a big part of my life and I'm not afraid to say that he's the best player in his position behind Mbappé, Neymar and Vinicius."
