Chelsea have confirmed that manager Jose Mourinho has left the Stamford Bridge club by 'mutual consent' after three trophy-laden years at the helm.
A club statement claims that the decision was reached after the launch of a new Chelsea documentary - Blue Revolution - at the Vue cinema in Fulham on Wednesday night, where an emotional Mourinho refused to talk to the press.
However, the rumours of his departure began earlier in the day and claimed that billionaire owner Roman Abramovich called crisis talks following Tuesday night's disappointing 1-1 draw with Norwegian minnows Rosenborg in the Champions League, at which the fractious duo had a furious falling out.
Mourinho is believed to have informed senior players of his departure following training on Wednesday and one of those players insists that the manager has not resigned but has been sacked by the Blues.
Mourinho's rocky relationship with Abramovich was public knowledge and despite an apparent thaw in relations last season the duo were again at odds over the role of £30million striker Andrei Shevchenko and the Blues' dour style of football even before Tuesday's result brought events to a head.
The Portuguese manager, who has won the Champions League with Porto and two Premier League titles as Chelsea manager, was the subject of continual scrutiny last season and hinted at an exit last summer when he admitted he 'was a bit fed up with certain things' at the club.
After three-years at the London club the self-styled 'Special One' is expected to attend training for the final time on Thursday, when he will say good bye to his players.
Chelsea lost their title to Manchester United last season and have started this campaign with some lacklustre displays.
Their last two Premier League games ended in a defeat at Aston Villa and a 0-0 draw at home to Blackburn Rovers, leaving them fifth in the table.
Tuesday's draw with Rosenborg Trondheim in the Champions League was watched by just 25,000 fans.
Chelsea's next match is against Premier League champions Manchester United at Old Trafford on Sunday.
