Real Madrid midfielder Lucas Silva has a €500 million (£421m) release clause in his contract, according to reports.
Details of the 23-year-old’s deal with the Champions League holders has been leaked to Le Soir via Football Leaks.
Silva was signed by Madrid for £9.7 million nearly two years ago but has made just nine first-team appearances.
The Br azilian, who spent last season on loan at Marseille, has been sidelined for two months due to a heart problem.
Silva has since returned to training, while Madrid are reportedly looking to loan the midfielder out again.
