The biggest stumbling block to this deal would be mancini. I think Rooney would happily move - it would be two fingers to un*ted, more money, a new start and wouldn't have to uproot. Un*ted would go for it because they are desperate for money and risk losing him for nothing. Ferguson has historically had no problem with letting his major players leave. Cook and the board would be happy to sign him because of the statement it would make and obviously money isn't an issue.
However, especially considering Mancini's recent comments about drinking etc etc, I'm not sure he would want a smoker who goes out with hookers. I think Mancini would turn it around and make a bigger statement by saying "to play for Manchester City is an honour and you have to derserve it on and off the pitch - no matter who you are".
Personally I just can't make my mind up what to think. I never thought I'd have to deal with these kind of emotions!!!!!
