Sky sources claim Ronaldo doesn't want to play football in Spain
Ronaldo has been linked with a move away from Real Madrid after being accused of tax evasion by the Spanish authorities.
Former club Manchester United and Ligue 1 giants Paris Saint-Germain have both been heavily linked with a summer transfer.
Ronaldo helped the club win La Liga and the Champions League last term, and has carried on his stunning form at the Confederations Cup with Portugal.
The 32-year-old has reportedly since changed his mind about leaving but reports in Spain are saying he will only stay if he gets his way.
