Chelsea manager Jose Mourinho has sensationally left the club, it is understood.
The Portuguese coach departed Stamford Bridge on Wednesday night after texting five senior players to say he was leaving.
Mourinho caught Chelsea's hierarchy by surprise after the premiere of the club's documentary 'Blue Revolution' by demanding talks at Stamford Bridge over his future.
Those talks continued late into last night, but his players were left in no doubt that the 1-1 draw against Rosenborg in the Champions League on Tuesday night was his last match in charge.
Mourinho is understood to have sent text messages to five players at 6pm on Wednesday night and by midnight the entire first-team squad were aware that he had left.
Mourinho led the club to two Barclays Premier League titles after joining the club in June 2004 but their disastrous start to the new season had taken its toll on him.
The Chelsea manager is set to report to the training ground at Cobham today to say goodbye to the players who won every domestic trophy during his time in England.
Juande Ramos, touted as a possible successor to Martin Jol at Tottenham, is among the coaches linked with his job.
Ramos watched his side lose 3-0 to Arsenal in the Champions League last night but may be tempted by an offer from the Blues.
Mourinho still had three years left on a contract, worth a staggering £6.5m a year, but the club's billionaire owner Roman Abramovich is prepared pay a huge slice of that in order to end their relationship.
At the time he signed the deal, Mourinho said: "My heart is with Chelsea and the fantastic group of players that I have but the vision of the owner and the board for the future of Chelsea is also one I want to be a part of.
"I cannot imagine another situation or another club where I could be happier. I am totally behind this project."
But Chelsea's board have become increasingly unhappy after the team's poor start to the season.
Chelsea are currently fifth in the Premier League, two points behind leaders Arsenal after six games, and their 1-1 draw with Rosenborg in their opening Champions League game on Tuesday night did not help his cause.
Mourinho's departure comes just days before they face Manchester United at Old Trafford.
Assistant Steve Clarke or director of football Avram Grant are set to take charge of team affairs on Sunday.
