SIR Alex Ferguson could be the broker behind any return of Cristiano Ronaldo to Manchester United.

The Portuguese superstar told his former Old Trafford boss weeks ago he was planning to quit Real Madrid.

Ronaldo is furious after Spanish authorities have accused him of trying to dodge multi-million tax payments.

And last night there were reports that he is interested in the possibility of a sensational return to the Theatre of Dreams – and a reunion with former Bernabeu gaffer Jose Mourinho.

United sold Ronaldo to Real in the summer of 2009 for £80m and they have tried to set up a deal for his return on at least one occasion since his departure.

At the moment, United are wary of being drawn into a transfer saga surrounding Ronaldo’s future and the general feeling at Old Trafford is that he will stay in Madrid.

Ronaldo’s advisers, though, have been told to find him a new club outside Spain because he is angry after being accused of evading tax of £14.7m between 2011 and 2014.

Paris Saint-Germain have a long-standing interest in signing him and AC Milan’s new Chinese owners have been in contact this summer with his agent Jorge Mendes.

China is another option, with the mid-season window today, but it is believed that at the age of 32, Ronaldo would prefer to carry on playing in one of Europe’s top leagues.

Madrid, though, will do everything they can to keep Ronaldo. The striker was avoiding talk over his future yesterday after helping Portugal earn a last-gasp 2-2 draw against Mexico in the Confederations Cup.

He said: “It was not the result we wanted, but we still believe in qualification because there are still two games left.”
