Cristiano Ronaldo has an astronomical €1billion release clause in his Real Madrid contract, according to his agent Jorge Mendes.
Ronaldo's future has been the subject of recent speculation, with reports linking hims with a return to Manchester United.
The 29-year-old has enjoyed a stunning start to the season, with three hat-tricks and 13 goals in just six games for the European champions.
However, it has been suggested that the Portuguese international is unhappy at the Bernabeu.
Chelsea have also been linked with the second-most expensive player of all time but manager Jose Mourinho was quick to shoot down the idea of a transfer, while Arsenal boss Arsene Wenger has also discussed the player.
But the most enduring speculation has come from Old Trafford, with Ronaldo's personal attachment to his former club putting Louis van Gaal's side in a strong position should he wish to leave.
However Mendes recently explained it would be "impossible to get him out of Madrid", and the 48-year-old has perhaps now revealed why.
Speaking to Spanish daily sports newspaper AS, Mendes said: "I no longer get calls from anyone asking about Cristiano. It's not worth them calling to ask for it. The price is that stated in his release clause - €1bn."
