Jose Mourinho's first spell as Chelsea manager is as fondly remembered for his witty and razor sharp soundbites as it is for the success and silverware he brought to Stamford Bridge.
On the day that the Portuguese manager's return to the Premier League was confirmed it is the perfect time to look back on some of the quotes that made him loved and loathed in equal measures.
A legend is born at his unveiling as Chelsea manager in 2004:
"Please don't call me arrogant, but I'm European champion and I think I'm a special one."
On his relationship with Chelsea owner Roman Abramovich:
"If Roman Abramovich helped me out in training we would be bottom of the league and if I had to work in his world of big business, we would be bankrupt!"
His reaction when police questioned him over whether his dog had a pet passport:
"The dog is fine in Portugal - that big threat is away - you don't have to worry about crime any more."
On his often troubled relationship with Arsenal, and in particular Arsene Wenger:
"Some clubs are treated as devils, some are treated as angels. I don't think we are so ugly that we should be seen as the devil and I don't think Arsene Wenger and David Dein are so beautiful that they should be viewed as angels."
On Wenger again:
"Wenger has a real problem with us and I think he is what you call in England a voyeur. He is someone who likes to watch other people. There are some guys who, when they are at home, have this big telescope to look into the homes of other people and see what is happening. Wenger must be one of them - and it is a sickness."
Mourinho defends putting a finger to his lips during the 2005 Carling Cup final against Liverpool, an action which resulted in him being sent to the stands:
"I don't regret it. The only thing I have to understand is I'm in England, so maybe even when I think I am not wrong, I have to adapt to your country and I have to respect that. I have a lot of respect for Liverpool fans and what I did, the sign of silence - 'shut your mouth' - was not for them, it was for the English press."
On his newly-cropped hairstyle:
"Look at my haircut. I am ready for the war."
On Liverpool's ghost goal which knocked Chelsea out of the Champions League in 2005:
"I felt the power of Anfield, it was magnificent. I felt it didn't interfere with my players but maybe it interfered with other people and maybe it interfered with the result. You should ask the linesman why he gave a goal. Because, to give a goal, the ball must be 100% in and he must be 100% sure that the ball is in."
On Barcelona's legacy:
"Barcelona are a great club. But in 200 years of history they have won the European Cup only once. I have been managing for a few years and I have already won the same amount."
On losing to Barcelona in 2006:
"When I saw Frank Rijkaard (then Barcelona coach) entering the referee's dressing room I couldn't believe it. When Didier Drogba was sent off (after half-time) I wasn't surprised."
On Barcelona's abilities:
"We have played against them four matches in two seasons. (When it was) 11 against 11 they never beat us. That is the reality."
On the state of his Chelsea squad, shortly before his departure from the club:
"No eggs, no omelette. And it depends on the quality of the eggs. In the supermarket, you have eggs class one, class two, class three. Some are more expensive than others and some give you better omelettes. So when the class one eggs are in Waitrose and you cannot go there, you have a problem."
On his return to Chelsea:
"In football I have never hidden that I have two great passions; Inter and Chelsea and Chelsea is more important to me. Now we are back together and we are ready to marry again."
On the conversation with Roman Abramovich which convinced him to return:
"I asked the boss 'do you want me back?' and the boss asked 'do you want to come back?' After a couple of minutes the decision was made."
