Sir Alex Ferguson is a household name in world football, and given the success he has had perhaps it should be rightly so, but I aim to explore the areas in which the Scot was not that good - and which could tarnish his status as world's best manager.
Ferguson is indeed remembered for his comparatively brief stint at Aberdeen, where he showed great promise in bringing home some European glory - but how different is that from any other manager who has had relative success at smaller clubs?
Why aren't we linking Neil Lennon, current manager of Celtic who won the Scottish league and also beat Barcelona in the Champions League, with the best jobs in Europe?
Ferguson was not that great at Aberdeen, with the exception of some minor successes; however, in the 1985/86 season he finished a shocking fourth place after winning the league in the previous season.
Let's face it: Ferguson has been at the best club in the world over the last 20 years and so we, as viewers, should be expecting, at least, copious amounts of silverware being brought back to the club.
Ferguson has also been handed a lot of money in his 26-year tenure at Old Trafford and although it is not thought of now, Manchester United did tend to throw about their money on a whim - and there have been some incredibly unsuccessful transfers that Ferguson has overseen.
Diego Forlán and Bébé, for example, are manifestations of the errors Ferguson is capable of making, and who can forget Dimitar Berbatov and his £30m price tag? Ferguson never really got the best out of the Bulgarian. Ferguson has also managed some of the best players in the world, facilitating his success just a little.
Ferguson is not a great man-manager as witnessed by the shock departures of David Beckham, Dwight Yorke and Ruud van Nistelrooy to name a few - and all these departures were put down to various degrees of conflict with the manager.
His rage was such that at one point during half-time in a game he had the audacity to kick a football boot in the face of David Beckham. If only he could have controlled his fury, then perhaps he could have reeled in a few more willing faces.
Ferguson has overseen 1500 games in charge of United and has seen countless wins, but he has not managed to leave behind his own strategy. Manchester United do not have a strategy exclusive to them, unlike the 'tiki-taka' style of Barcelona or the 'total football' gameplay of Bayern Munich and not even the flair and guile that Chelsea have been known to play with this season.
With the resurgence of Manchester City, United are no longer the dominating force they once were in Manchester, and one would think that a priority of his would be to quell the threat posed by his closest rivals.
However, Mancini's City have quite simply embarrassed him in recent seasons winning five out of six meetings, including a 6-1 drubbing of United - Ferguson's worst loss at Old Trafford.
Ferguson has performed as expected at Manchester United but has done nothing special with his time at United.
