'I stay until they want me not to stay. No club moves me from Chelsea until Chelsea wants me to move because I want to be where I am loved' - Jose Mourinho, January 2014The 'Special One' returns as 'the Happy One', calmer and better than before. Grayer; perhaps less flamboyant, even opting for a self-inflicted crew cut (he borrowed the clippers from Fernando Torres). But he's still the Special One, still confrontational, passionate, full of chutzpah. Mourinho is a masterful tactician, and surely now the best boss in the business.In his first stint at Stamford Bridge he won two League titles back to back, the FA Cup and two League Cups, and included a still-unsurpassed Premier League points tally record of 95 in the 2004/05 season. And after six years spent sweeping all before him with Real Madrid and Inter Milan, his absence certainly made the heart grow fonder. Chelsea's army of fans love him every bit as much as they used to, and those heady days beckon once more for Chelsea since he replaced the hugely unpopular Rafa Benitez in June 2013.One thing has changed, though - Chelsea are no longer the richest club around. But when his new Blues demolished Manchester City at the Etihad, Gary Neville heralded Mourinho's master class: 'He's shrewd, he's smart and he calls it on. He's good and he knows he's good.'This updated and expanded edition of Harry Harris's 2007 biography brings the story right up to the end of Mourinho's first season with Chelsea since he left in 2007, showing exactly why English football would be infinitely poorer without the colourful and commanding presence of the 'Special One'.
