The Portuguese star, 22, will be presented with a deal worth £140,000 a week that would tie him to Old Trafford until 2014.
That would see him leapfrog Chelsea skipper John Terry, who has a contract worth £130,000 a week. Ronaldo, who has scored 27 goals already this season, would earn an incredible £7million a year with his new deal.And that would send Ronaldo soaring to the top of the Old Trafford pay stakes ahead of Wayne Rooney and Rio Ferdinand.
Manager Sir Alex Ferguson has only just been given the go-ahead by the Glazer family to break United`s wage structure but Old Trafford sources are confident Ronaldo will put pen to paper in the summer.
United have also been alerted to the risk that they might lose Ronaldo in two years after a landmark ruling this week by the Court of Arbitration for Sport.The decision means that Ronaldo could break his contract with two years remaining by handing over the remaining value of his wages.
That would see him become available in 2010 for a mere £10m as he is currently on £100,000 a week. The ruling means all top clubs will be forced to review the contracts of their stars long before they expire.
