Cristiano Ronaldo is interested in the possibility of returning to Manchester United this summer, Sky sources understand, but what should his transfer fee be?
United sold Ronaldo to Real Madrid in the summer of 2009 for £80m, then a world record transfer.
The Real Madrid forward wants to leave Spain and a source close to the player says United are very close to his heart.
Paris Saint-Germain have a longstanding interest in signing him and AC Milan's new Chinese owners have been in contact with Ronaldo's agent Jorge Mendes this summer.
China is another option, with their mid-season window opening on Monday, but it is believed that at the age of 32, Ronaldo would prefer to carry on playing in one of Europe's top leagues.
Having signed a new five-year contract at Real last November - which features a release clause of 1bn euros (£875m) - any club that comes in for Ronaldo would have to spend big in terms of transfer fee and also wage.
Forbes recently reporting that he topped the highest-paid athletes list for 2017, based on salary and endorsements.
Taking into account the transfer fee alone, is he worth more than current world-record signing Paul Pogba? Cast your vote below
