Big spending Monaco have shown "real interest" in signing Zenit St Petersburg forward Hulk, according to the player's agent.
The 26-year-old has endured a turbulent first season in Russian football following his move from Porto in September.
And Hulk, who had a transfer request rejected in January because of UEFA regulations forbidding a player appearing for three different clubs in the same season, is said to be attracted to the ambitious project being developed in Monte Carlo.
According to the player's agent, Teodora Fonseca, the interest is mutual.
"I know people at Monaco. They have not contacted me, but there has been speculation and the interest is real," he told Le 10 Sport.
Should a move materialise, Hulk would be reunited with former Porto team-mate Radamel Falcao, who is expected to complete his big money move to Claudio Ranieri's team in the coming days.
Monaco have already wrapped up the signings of Porto duo James Rodriguez and Joao Moutinho for a combined fee believed to 70 million euros.
