Jose Mourinho has a developing crisis to deal with as he prepares for Chelsea's home match against west London rivals Fulham at Stamford Bridge on Saturday.
Chelsea fans were delighted when Mourinho was confirmed as the club's manager for the second time in early June.
'The Special One' had guided Chelsea to their first top-flight domestic title in 50 years - the 2004-2005 Premier League title - and a host of other trophies before he left the club in September 2007 "by mutual consent," after reports of a falling out with Russian owner Roman Abramovich.
With his relationship with Abramovich patched up, Mourinho returned to Stamford Bridge as replacement for unpopular interim manager Rafael Benitez.
The 50-year-old Mourinho got off to a winning start in the Premier League against Hull City Tigers (2-0) and Aston Villa (2-1), before securing a hard-earned goalless draw against Manchester United at Old Trafford.
But Chelsea have lost three matches in a row across separate competitions. Bayern Munich beat the Blues on penalties after a 2-2 draw to win the UEFA Super Cup on Aug. 30. Everton then beat them 1-0 at Goodison Park last Saturday as the Premier League resumed after the international break. The most recent reverse was a shock 2-1 home defeat by Swiss side Basel in a Champions League Group E match Wednesday night.
Mourinho was defiant when he talked to the media after Chelsea's first home defeat in 29 Champions League group games.
"I am the manager, I am responsible for everything, especially after a bad result," he said. "I don't think it's the time to speak about individual performances. We lost and we lost as a team. And I am responsible.
"We still believe in each other. We need to keep together, stick together and try against Fulham (on Saturday) to get the result to wake up the team for a smile."
Fulham boss Martin Jol is also under fire following his side's slow start to the new Premier League campaign.
The Cottagers drew 1-1 at home to West Bromwich Albion last Saturday after conceding a stoppage-time equaliser to the visitors and there were cries of "Jol out" from a small but vocal group of fans at the end of the game.
Fulham have picked up only one point from their last three league matches after making a winning 1-0 start at Sunderland on the first day of the season.
Jol has responded by suggesting some Fulham supporters may be expecting too much of their team.
"It's hard to fight expectation levels and maybe a minority feel we should be in the top four," said the 57-year-old Dutchman. "We are 12th in the league and that's maybe where I feel we could finish, maybe ninth or 10th. We are doing OK. We are stronger than we were last season, or September last year."
Chelsea took four points off Fulham last season, cruising to a 3-0 win at Craven Cottage on Apr. 13 on the back of a John Terry brace plus a goal by David Luiz. The sides played out a goalless draw at Stamford Bridge last November.
Fulham have just one win over Chelsea in their last 24 meetings, losing 13 times and drawing 10.
Mourinho family loyalties could be divided on Saturday after it was reported this week the Chelsea manager's 14-year-old goalkeeper son, Jose Mario, had joined Fulham after impressing during a one-month trial.
