Real Madrid's Cristiano Ronaldo has often been linked with Paris Saint-Germain, and Los Blancos have now set their price tag for the Portuguese superstar.
The Spanish giants' president, Florentino Perez, has stated that Real would only allow Ronaldo to leave for PSG if they fork out €1 billion, which would meet the forward's release clause.
"If PSG want Ronaldo, it's easy – they have to pay the release clause: €1 billion," he told Cadena COPE.
"No one is a prophet in football, but we don't want to sell him in 2016.
"There are still three years left on his contract."
The French side denied making a bid of about €120 million for the 30-year-old earlier this year, although they remain strongly interested in his services.
It's widely believed Ronaldo will make a move to Major League Soccer in the US once his contract at Real ends in 2018.
Ronaldo has played 302 games for Real, scoring 313 goals and assisting a further 103 strikes.
