Real Madrid manager Jose Mourinho is, without doubt, one of the greatest football coaches in the modern era.
Never very far from the headlines, the Portuguese tactician has, over the years, built an unwanted reputation for being arrogant, disrespectful and almost always controversial.
But, like him or not, 'The Special One' - as he so famously labelled himself upon his arrival at Stamford Bridge, to take over as Chelsea manager in 2004 - boasts an enviable list of record-breaking accomplishments, that put him in the very top bracket of bosses in the world.
Nobody splits opinion quite like Mourinho, whether people are talking about his early days at FC Porto, when he guided the Primera Liga giants to the Champions League trophy, or his ill-fated spell in England with Chelsea, which ended after three-and-a-bit years, after winning two Premier League titles, two League Cups and one FA Cup.
Two years in Italy followed, at the San Siro, where Mourinho won another Champions League crown, this time with Inter Milan, in addition to back-to-back Serie A titles and a Coppa Italia trophy, before taking up his current post in the Spanish capital with Liga giants Real Madrid.
Since arriving at the Santiago Bernabeu in May 2010, the Portuguese has added a Copa del Rey trophy and the Primera Division title to his list of achievements, and is now looking to become the first ever manager to win three European Cups with three different clubs, in what will be Real Madrid's landmark tenth crown.
However, recent reports of a turbulent relationship between Mourinho and a number of players and staff, has put the manager under increased pressure in Spain.
Only yesterday, the Daily Telegraph reported that his future at the club rests on the outcome of Real Madrid's forthcoming last-16 clash against Manchester United next month, with assistant coach Aitor Karanka already being viewed as a potential caretaker manager until the summer.
Whilst it would be a sour end to an ultimately successful three-year spell in charge of Real Madrid, Mourinho would not be short on offers for his next job. He has openly stated a desire to return to the Premier League, with many suggesting that he could succeed Sir Alex Ferguson at Manchester United, when the time finally comes for the Old Trafford legend to retire.
Today, Mourinho celebrates his 50th birthday, and in tribute to 'The Special One' on his half century, GiveMeFootball has decided to take a look back at his career in numbers…
