FC Porto, the Portuguese Primeira Liga champions, have set a price of €25 million (N10.8bn) for Nigerian defender Zaidu Sanusi.
Zaidu Sanusi has generated interest from clubs in the English Premier League.
Fulham, Crystal Palace, Brighton & Hove Albion, and Everton are all said to be interested in signing the left-back.
According to Portuguese newspaper O Jogo, the Nigerian has a €50 release clause in his contract, but Porto is willing to sell him for half that amount.
Sanusi, who is represented by super agent Jorge Mendes, is considering a summer move to England.
Last season, he scored the title-winning goal for Porto.
