The former United star wishes to quit Real Madrid and return to Old Trafford, a day after boss Alex Ferguson admitted he would love him back, reports The Sun.
Ronaldo, 27, has told friends as well as ex-Red Devils team-mates he wants to "come home", adding that he is keen to move back to a club where he is loved like no-one else and not just another star. Also he wants to work again with Fergie.
The news comes days after Real Madrid were pitted against United in a mouthwatering Champions League tie.
But Ronaldo admits a deal at the moment seems "impossible" due to the vast sums involved, which Fergie conceded.
Ronaldo has fired 170 goals in 169 games since his move to Real in 2009.
He has a one-billion euros get-out clause, which is around 810 million pounds, on a deal that has two and a half years left to run.
Madrid would want around 122 million pounds for their prize asset. But selling him would easily cost club president Florentino Perez re-election this summer. (ANI )
