Former Barcelona star Igor Korneev rates Benfica striker Goncalo Ramos in the €200m class.
Korneev made the claim using Chelsea's deal for former Shakhtar Donetsk winger Mykhaylo Mudryk as a yardstick.
He told Sport.ru: "If Mudryk was bought for €100m, then he could cost €200m. But I believe he will be transferred around 120 million.
"Basically he has no weak points. He is fast, strong, we realized that he can beat one or two opponents in a small space. In an absolutely unbelievable way he turns and changes completely direction.
"And I'm not just talking about his performance at the Worlds. He plays well with both feet."
