The United board will NOT bring in Mourinho if they suspect he may leave himself or be sacked by them within a few years as is consistent with his previous roles in Portugal and England and possibly Inter as he looks like he may be looking at leaving Italy to return to a Premiership club.
The United board, many of whom were seated in the late 1980's have extreme patience and vision and are willing to forego a season or two to lay foundations of an empire rather than go for a quick fix. This is evident when Ferguson paid money for Rooney in 2004. We had Ruud, had bought Saha earlier that year and just bought Alan Smith and despite his talent, many questioned why we were buying Rooney as well rather than a top class midfielder we so desperately needed that year but Fergie knew in Rooney, we'd have a player who would be at the cornerstone of our team for a decade or more and effectively blew our budget for the whole season on the one player, meaning we played with a skeletal midfield that year and the year after, employing Giggs and O'Shea for the majority of it.
Despite Ferguson's massive success, attributes must also be given to our board for their support and patience whereas many other clubs would have been pressing for success. Not us. We make massive amounts of revenue regardless of a Premiership-less season.
The board will be looking at the continuance of our dominance over a generation as Ferguson has done, not a quick fix which may result in instability if the manager quits or is sacked due to his impudence. With new managers come new players, when managers leave, so do players. United could not allow that sort of revolving door policy that we see at Spurs and other clubs due to their high numbers of staff turnover when in reality if the Spurs board were more patient, we would see Spurs challenging a lot more than they have as they have had the staff and resources to do so, just shit chairmen and board backing......
