Benfica have told Manchester United and Wolves their star striker Carlos Vinicius cannot leave for anything less than his €100million release clause.
The Premier League rivals have been linked with a summer move for the Brazilian striker.
Vinicius, 25, is the leading scorer in the Portuguese top flight after hitting 15 goals in an impressive debut season for the second-placed side.
Reports in Portugal claim Wolves could be willing to go as high as £53m for the ace, who is under contract until 2024 and has also been named as a potential United target.
But Mirror Sport understands Vinicius has a huge release clause worth £88m and Benfica are standing by it after signing him from Napoli for £15m last summer.
The striker is represented by Jorge Mendes, who has brokered numerous deals to Molineux as he is close to the club's Chinese owners.
Vinicius was previously on their radar last summer but Wolves sources suggest the club are not now expected to break the bank in the wake of the coronavirus pandemic.
Their current transfer record is £30m for striker Raul Jimenez last year after a successful loan.
Benfica boss Bruno Lage has said he wants to build his team around Vinicius.
"He is the right man to lead Benfica for many years", Lage said of the forward.
"He is the man who has brought joy to Benfica fans. We are happy with him and he is happy with us. That is what matters."
United have been linked with a move for Vinicius amid uncertainty over the future of Odion Ighalo, who joined the Red Devils in January on loan from Chinese club Shanghai Shenhua.
However, Portuguese publication A Bola reports that no club is currently willing to match Benfica's €100million valuation.
