It wasn't that at all though, that's just what you've decided it was.
The one time he handed in a transfer request he had legitimate concerns about the investment in the squad.
We won a League and European Cup double in 07/08, and Berbatov was the only statement signing that we made the following summer. When the next season had ended and we'd retained the league and were one game from retaining the CL, both Tevez and Ronaldo left, and our midfield was still a problem area, particularly as Hargreaves was still in the midst of severe injury problems.
We'd just fought Liverpool off for the first time in forever, City were investing hundreds of millions in playing staff (including Tevez), and Chelsea were still very formidable. He wasn't requesting a ton of new super signings, but he was looking at a squad that had just lost Ronaldo and Tevez and had a gaping hole in its midfield, with the summer reinforcements consisting of a 30-year-old Owen on a free, Valencia from Wigan, who was very much unproven at that time, and Diouf and Obertan, who were gambles for the future.
I'm not saying anything was a media hoax, but the links to City were almost entirely media speculation, if not entirely. They took Rooney's transfer request and City's heavy investment in their squad (combined with the signing of Tevez) and linked them together to formulate the "Rooney wants to go to City" narrative that people like to trot out to this day.
