A reflective Jose Mourinho has returned to London for another stint as manager of Chelsea, having transformed himself into the "Happy One", hungry for fresh glory at the English Premier League club.
The 50-year-old Portuguese told a packed news conference at Stamford Bridge he has the same passion for football and his job, but he is a different person - a very happy person because its the first time he's arrived at a club he already loves.
Mourinho led Chelsea to back-to-back titles during his first spell between 2004 and 2007 but left after a reported falling out with the club's owner Roman Abramovich, though he insists he left "by mutual agreement", albeit with a heavy heart.
Mourinho famously described himself as the "Special One" at his first news conference for Chelsea nine years ago.
