Jose Mourinho has won multiple league titles (across 4 countries), the Champions League twice, and many other honours that would accumulate to suggest he's one of the best football managers of his generation.
However, his plain arrogance and decision making has prevented him from being placed up there with the likes of Sir Alex Ferguson, Matt Busby and Bob Paisley.
Mourinho busted onto the stage in an eccentric interview after becoming Chelsea manager in 2004, and after referring to himself as 'The Special One', his arrogance was plain to see.
After talking the talk, everybody in football was intrigued to see whether he was capable of walking the walk. And initially, he did just that- winning Chelsea their first league title in 50 years. However his complete lack of class soon soured his Chelsea success, eventually seeing him leave the club a few years later.
After Chelsea's Champions League tie against Barcelona at the Nou Camp in 2005, Mourinho accused the then Barcelona manager, Frank Rijkaard, of making a suspicious visit to the dressing room of referee, Anders Frisk. Something which was thoroughly denied. In the aftermath, Frisk received so many death threats that he saw fit to retire. Mourinho was branded an 'enemy of football' and handed a two match ban. And so the discourtesy began. Although not confirmed, it's been implied that Mourinho got around this two-match ban by delivering messages to his fitness coach via an earpiece. Whether true or not, Mourinho displayed a complete unprofessionalism in the entire saga, which simply cannot see him as one of the best managers of his generation.
Frank Arnesen, and coupled with the on-going friction with Roman Abramovich, he eventually left Chelsea in 2007. Mourinho became engaged in a power struggle between himself and sporting director,
After a brief spell in Italy, Jose moved onto to manage Real Madrid, where his managerial short-comings were truly exposed. He walked into the Bernabeu with the usual 'Special One' talk, however they needed more convincing. They wanted to see proof. Real Madrid are traditionally a class football club, and Jose Mourinho simply didn't fit that fold, hence his brief stay.
Inheriting a squad including the likes of Cristiano Ronaldo, Kaka, Iker Casillas, Karim Benzema and Xabi Alonso, all things considered, he failed. He was handed the platform to achieve greatness, yet his obsession with beating Barcelona got in the way of what could have been. The first El Clasico of Mourinho's reign ended in a 5-0 defeat. Being an icredibly egotistical man, this crushed him. From then on, he put every effort into beating Barcelona, perhaps refusing to look at the bigger picture, resulting in points being dropped in relatively easy matches, and a complete failure in Europe.
Winning the league in 2012 was enough to convince most that the 'Special One' was as good as he proclaimed to be. However, this was his only real success at Madrid, and so for me the short-comings inevitably overlook this one achievement.
His idiocy continued to prevail. Poking the eye of Tito Vilanova and being sent-off in the 2013 Copa del Rey final for, once again, showing a lack of respect towards officials, serve as two examples.
His fall out with club legend Iker Casillas proved the last straw for Real Madrid fans, making his eventual exit in the summer inevitable. And I'm sure he won't be missed.
Jose Mourinho looks set to return to Chelsea to the utter joy of their fans. And after failing to compete for the league title for a few years now, that's understandable. With Mourinho, immediate success seems inevitable.
However it's only a matter of time before he presses the self-destruct button once more, and leaves the west London club in a worsened state to what they were in beforehand.
