The Sun says Ronaldo put Manchester giants City and United on red alert after admitting he wants to quit Real Madrid.
A source said: “Yes, Cristiano told president Florentino Perez he wants to leave the club.”
It follows the Portugal superstar’s bombshell on Sunday after scoring twice against Granada.
Ronaldo, 27, did not celebrate either of his goals and said afterwards: “I am sad and the people at the club know about it.
“It’s about professional issues. I can’t say any more.”
Megabucks City and his old club United will keep a close eye on developments – along with Chelsea.
