Roma have warned they must cough up big to sign Shakhtar Donetsk winger Taison.
The Brazilian, 31, wants to join his former Shakhtar coach Paulo Fonseca at Roma.
But agent Diego Dornelles told RomaPress: The situation is stalled by Shakhtar's refusal to negotiate.
"They want the buyout clause paid. Another Italian side even tried to negotiate but they were unsuccessful.
The clause is 30m."
