The England forward ended an intense week of speculation about his future yesterday lunchtime when it was confirmed he had agreed a new contract with the Old Trafford outfit.
Rooney will become the highest-paid player in United history, set to earn around £150,000-a-week, having received assurances from the Glazer family about the future direction of the club.
But he will not be able to assist United on the pitch for a little bit as he spends the next three weeks recovering from an ankle injury, which was the cause of so much angst in the first place.
The recovery period will probably include the first Manchester derby of the season at Eastlands on November 10.
However, when he does return shortly afterwards, Rooney is determined to shake off the lethargy that has seen his form collapse to the extent that he has not scored a goal in open play since March.
"I certainly can't wait to pull on the red shirt again," he told MUTV.
"I am gutted to be injured. I just want to be out there playing, get back to form and doing what I do best. And I will be back to my best. I have no worries about that."
Rooney is aware of the upset his outspoken comments, questioning his team-mates' talent, have caused.
He has already been assured of Sir Alex Ferguson's support and Rio Ferdinand has given dressing room approval.
In all probability, United's supporters will be bellowing from the rafters too.
But if there are any remaining dissenters, they will be won over in the only way the Merseysider knows how.
"I am sure the fans have been upset over the past few days with everything they have heard in the media," he said.
"But I care for this club. I want to be here and I want to continue being successful at this club.
"It might take time with some fans. But I am going to be giving 100%, the same as always, to try and build that relationship back."
If there is one thing United's fans should be thankful for, it is that assurances have been received from the Glazer family about funding for the future.
"I have spoken with the manager, David Gill and the Glazers," he said.
"All of them have confirmed to me this is the right club to be at and this club will continue being successful and winning things."
