Last season they finished runners-up to Manchester United but won both the FA Cup and Carling Cup, a trophy they had also collected in 2005.
His achievements also saw him voted as Premiership manager of the year in 2005 and 2006.
MOURINHO'S CHELSEA RECORD
2 June, 2004 - Appointed manager
27 February, 2005 - Wins Carling Cup 3-2 v Liverpool
30 April, 2005 - Beat Bolton 2-0 to win Premiership title
4 May, 2005 - Signs new five-year contract
29 April, 2006 - Beat Man Utd 3-0 to win Premiership again
27 February, 2007 - Beat Arsenal 2-1 to win Carling Cup
19 May, 2007 - Win FA Cup by beating Man Utd 1-0 at Wembley
19 September, 2007 - Leaves Stamford Bridge
However the Champions League trophy eluded the club and this season's campaign started with Tuesday's shock 1-1 result against the Norwegians in front of a crowd of just 24,973.
It was their third successive game without a win following a 2-0 defeat at Aston Villa and a goalless draw with Blackburn in the Premier League.
Those results have left Chelsea fifth in the table - two points behind leaders Arsenal and with a visit to Manchester United to come on Sunday.
He did have one unique record during his reign in never losing a home league game at Stamford Bridge.
Mourinho signed a five-year contract in 2005 and quashed speculation in January that he would leave Stamford Bridge in the summer by saying he was happy to see out his deal if he received "real support" from the club.
