The Manchester Evening News says United and City were on red alert last night as news of a rift between Ronaldo and Real Madrid emerged following the Spanish champions 3-0 win over Granada.
“I’m sad because of a professional issue and the club know why,” he said. “That’s why I didn’t celebrate the goals, because I’m not happy. The people [at the club] know why.
“I won’t talk about this any more and I will concentrate on Portugal for now. There are more important things.
“The people at the club know about this. I can’t say any more.”
Sir Alex Ferguson – who reluctantly allowed Ronaldo to leave Old Trafford in 2009 – would relish the opportunity to work with the prodigious talent again.
Rivals City will also monitor the situation – and will feel they have the financial clout to back up their interest.
