Ferguson convinced his star striker to stay at the club in 2010 when the England international previously requested a move away from Old Trafford (Daily Mail).
The striker's future could now be the first issue Moyes has to resolve if he succeeds Ferguson. The Everton manager is expected to be confirmed as the new United manager after meeting with Goodison Park chairman Bill Kenwright in London on Wednesday.
Moyes, of course, was Rooney's manager at Everton before his £27 million move to Manchester United in the summer of 2004 (BBC Sport).
However, Moyes took Rooney to court for libel in 2008 over claims the striker made in his autobiography, and the striker settled out of court with his former manager (Daily Telegraph).
As Bleacher Report writer Allan Jiang noted on Wednesday, the two men have settled their differences over that issue, but a question still remains over whether Rooney will feature under Moyes.
It all adds an intriguing subplot to the forthcoming events if Moyes accepts the challenge of succeeding Ferguson at Old Trafford.
