City have decided to break the bank to attract the Real Madrid star to the Etihad if he becomes available this summer.

And they have told the Ronaldo camp they are prepared to beat any financial offer United put to him - meaning they could pay more than £300,000-a-week to get their man.

United have spent the past five months trying to put together a deal to bring the 28-year-old back to Old Trafford, and the emotional pull for Ronaldo is huge.

City know that would be a major hurdle to overcome, but Starsport understands both chief executive Ferran Soriano and football director Txiki Begiristain have told the player’s representatives they are deadly serious in their interest.

And they have made it clear that if Real are open to letting the Portugal ace leave, they will go as far as it takes to blow their Manchester rivals out of the water.

City chairman Sheik Mansur has made it clear to Soriano that should Ronaldo come onto the market, City have to do everything possible to clinch his signature.

Ronaldo has two years left of his current deal in Spain, but despite making public claims a new deal is close, Real have yet to make ANY formal contract offer.

That has increased optimism at United that they can seal a stunning summer transfer - though City’s late interest will cause concern at Old Trafford.
