To many, including himself, Jose Mourinho is the most successful football manager in the world - the 'special one'.
He has won league titles in all of the countries he's worked in. But he is also divisive; famous for igniting rows with opponents and provoking referees.
Mourinho was born into football. His father was a goalkeeper who once played for Portugal. The young Jose wanted to be a player too but after short spells in minor clubs he realised coaching offered him a brighter future.
Fast forward 25 years and this week Mourinho has been named Manchester United's new manager.
