Juventus superstar Cristiano Ronaldo has reportedly set Real Madrid one condition if he is to consider making a return to his former club.
Despite Ronaldo being contracted to the Bianconeri until the end of next season, the 36-year-old has been linked with a move away from Turin following the club's elimination from the UEFA Champions League to FC Porto.
The reigning Serie A champions are reportedly considering offloading the five-time Ballon d'Or winner in order to ease the club's growing financial concerns, which were compounded following last week's exit from Europe's premier club competition.
Ronaldo's apparent availability has put a host of Europe's biggest clubs on red alert, including Paris Saint-Germain and former side Manchester United, but it is Los Blancos who appear to hold the advantage in the race to secure his services.

However, Italian publication Calciomercato claim that the record 34-time LaLiga champions have been set one non-negotiable condition before such a move can take place – that manager Zinedine Zidane remains at the club.
The Portuguese forward previously enjoyed a highly-successful spell under Zidane's leadership in Madrid where the duo combined to help the club win no fewer than nine major honours during their time together, including three UEFA Champions League crowns.
A possible reunion appears to be on the cards after the Frenchman refused to play down the possibility of Ronaldo's return earlier this week, even going so far as to admit that rumours could be true.
"Yes, it may be," Zidane told Sky Sport Italia. "We know Cristiano, we know the person he is and everything he has done here. But now he's a Juventus player and we must respect this. Let's see what the future will be. I was lucky enough to coach him and he is very impressive. Right now, he's helping Juventus."
