The Sun's Charlie Wyett claimed on the Sunday Supplement that Wayne Rooney has signed a new four-and-a-half year contract with Manchester United after "buying into David Moyes' philosophy" at Old Trafford.
The journalist said that the 28-year-old England forward has signed a contract worth £300,000-a-week and was in line to succeed Nemanja Vidic as United's next captain.
Sky Sports sources were told on Sunday morning that Rooney has yet to sign a new deal, contrary to the reports.
Wyett, though, was adamant that the deal was done and Rooney had put pen to paper when pushed on the story on the Sunday Supplement.
"We are saying that he has not just agreed, but he has actually signed," he said. "Obviously that has yet to be announced for Manchester United.
"I think he realises it is the best place for him still. I know others thought he might go to Chelsea or elsewhere, but I think Moyes has had a series of meetings with him and convinced him to stay.
"I think Rooney will be the next captain of Manchester United and I think that it is a boost for Moyes. He is obviously going through a difficult spell.
"It is a boost for United and I think that all Manchester United fans will be delighted because they do need him. He will be there for the next four and a half years now."
Pressed on the situation, Wyett said: "Rooney has just signed so I am sure that in the next week or so, it will happen. It was the same with [Arsene] Wenger.
"These days, we have to have a big announcement rather than in the old days when it would just be a picture in the local paper with a player signing a contract. But it is a very different era now."
Wyett believes that the news will be welcomed by England manager Roy Hodgson as well, as the United striker will be able to focus entirely on the World Cup in Brazil this summer, rather than being distracted by thoughts about his future at club level.
"I think it is good for Roy Hodgson," he added. "Roy is in Brazil this week and to have a key player going into a major tournament settled, with his future sorted, will be a benefit to Hodgson and England as well."
