Former Chelsea manager Jose Mourinho certainly made his mark during his three years in English football. Here, we look at a number of controversies he has been involved in.
• ANDERS FRISK
Mourinho accused Barcelona boss Frank Rijkaard of going into referee Anders Frisk's room at half-time during their Champions League clash at the Nou Camp in 2005, in which Didier Drogba was controversially sent off. His remarks earned him a two-match touchline ban.
• ASHLEY COLE
Mourinho was involved in a tapping-up row with Arsenal after it was alleged he had met the then Gunners full-back in a hotel with other Chelsea officials. Fined £20,000 by the Premier League.
• SIR ALEX FERGUSON
Mourinho hit out at the United boss after the first leg of a Carling Cup semi-final in January 2005. 'Alex was clever putting pressure on the ref at half-time,' he said. 'It was whistle and whistle, fault and fault, cheat and cheat.' It earned him a £5,000 fine for improper conduct.
• ARSENE WENGER
Becoming increasingly annoyed by comments from Arsenal manager Arsene Wenger about his Chelsea team, Mourinho hit out at what he perceived was an obsession by the Frenchman. He claimed he had compiled a 120-page dossier of Wenger remarks and labelled the Gunners boss a 'voyeur'.
• ANDREW JOHNSON
Everton submitted a formal complaint after Mourinho accused Toffees striker Johnson of diving. 'He's dangerous for opponents because you can't trust him and I was not happy with that, but I think he was a bit embarrassed and he behaved very well after that,' said Mourinho, who later apologised.
• LIONEL MESSI
The Johnson incident was not the only time Mourinho had complained about an opponent's antics. 'How do you say cheating in Catalan?' he said after a fiery encounter with Barcelona, suggesting Messi had made the most of a foul to get Asier del Horno sent off.
• RAFAEL BENITEZ
Despite his domestic domination of the Spaniard during the Blues' title-winning seasons, he could never plot a course past Benitez in Europe. Twice Liverpool dispatched Chelsea on penalties in the Champions League semi-finals, and their relationship became ever more frosty. As Benitez put it: 'We were good friends until Liverpool started winning, then he started changing his mind.'
• ROMAN ABRAMOVICH
Although neither ever went public with their mutual dissatisfaction, Mourinho and his employer were long assumed to be at loggerheads. Mourinho was not thought to have wanted Andriy Shevchenko and he failed to get the best out of his undoubted talent. The transfer money dried up in January and things were never the same afterwards, with Abramovich's appointment of Avram Grant as director of football this summer apparently serving only to rile Mourinho further.
