Sources close to Chelsea claim Roman Abramovich would be prepared to splash out over £30million for Rooney and match his £250,000-a-week United salary. It is believed Abramovich is determined not to be outbid by Paris Saint-Germain for Rooney and will blow any interest from Arsenal out of the water.
New United manager David Moyes has made Rooney's future his top priority and will soon speak to the 27-year-old at Old Trafford.
Those talks may well decide whether or not Abramovich gets his man. Jose Mourinho is expected to return to the Blues for a second spell as manager and the Portuguese is a big fan of Rooney.
A source revealed: "Chelsea want to make sure that if Wayne leaves United, there is only one place he will go.
"They are prepared to spend, big, big money on Rooney and they have told United that.
