Jose Mourinho has been named Chelsea manager for a second time.
Mourinho told Chelsea TV: "In my career I've had two great passions - Inter and Chelsea - and Chelsea is more than important for me.
"It was very, very hard to play against Chelsea, and I did it only twice which was not so bad.
"Now I promise exactly the same things I promised in 2004 with this difference to add: I'm one of you."
Chelsea legend Ron Harris, who played for the Stamford Bridge side between 1961 and 1980, believes that the vast majority of fans will be happy with the return of their former boss.
He told Sky Sports News: "I think 95 per cent of the Chelsea supporters are pleased Jose is back. I feel that the supporters will be more than happy and I think it is a pat on the back for Roman Abramovich in bringing Jose Mourinho back to the club."
And former Blues forward Tony Cascarino is eager to see Mourinho back in front of the English media, with his first press conference scheduled for next Monday.
He added: "Jose Mourinho's first press conference is going to be like seeing the Rolling Stones or The Beatles! But let's put it in perspective, Mourinho is a very talented manager. There is no doubt about that. You only have to look at his previous clubs."
And Sky Sports' Revista de La Liga Scott Minto, who also played for Chelsea, believes Mourinho will make a seamless transition from Real back to west London.
He said: "I do not think it is any bigger than the Real Madrid job. I think that is the biggest job out there.
"I would almost equate Chelsea to being the English equivalent of Real Madrid in the sense that, under Roman Abramovich, they have spent so much money it is not just about winning trophies anymore."
Sky Sports 1HD will screen a number of programmes from 10pm on Monday night to celebrate Jose Mourinho's return to Chelsea, including Football's Greatest Managers, highlights of the Blues' first Premier League title win and their League Cup triumph over Liverpool. Click here to watch online.
