The Premier League champions have endured a nightmare campaign so far, and a team that strolled to the title last season have already lost half of their 10 games in the division so far.
Victories have been thin on the ground for Mourinho's men this term, and the Portuguese has left a litter of excuses in a increasingly desperate attempt to deflect the fact that neither he nor his team have performed anywhere near an acceptable level.
The Blues were held to a 2-2 draw at home to Swansea City on the opening day of the season, and Mourinho got his excuses in early after Thibaut Courtois' sending off and subsequent fume at physio Eva Carneiro, who saw her days swiftly numbered after angering the boss for administering aid when Chelsea were defending a late set-piece.
"I wasn't happy with my medical staff because even if you are a medical doctor or secretary on the bench, you have to understand the game," Mourinho told the press, as reported by Sports Mole.
"If you go to the pitch to assist a player, then you must be sure that a player has a serious problem. I was sure that Eden (Hazard) didn't have a serious problem. He had a knock and was very tired.
"My medical department left me with eight fit outfield players in a counter attack after a set piece and we were worried we didn't have enough players left."
The surrounding furore masked the fact that Chelsea were below par at home to Garry Monk's side, but there was nowhere to hide on August 16 when title rivals Manchester City hammered the champions 3-0 in front of the biggest Etihad crowd in Premier League history.
However, Mourinho tried once again to take the heat off his underperforming stars, branding the reverse as a "completely fake" result to Sky Sports.
"The best team in the first half won the game. The best team in the second half was Chelsea for sure," he said. "We had a difficult first half, we didn't create a lot and our goalkeeper made a few important saves.
"Second half everything was different. If the 1-0 was a doubtful result at minute 70, 3-0 is completely fake. At 1-0 Chelsea were the best team for the whole second half."
A home defeat to Crystal Palace once again saw Mourinho reaching for mitigation, this time slamming a refereeing display from Craig Pawson by telling Sky Sports: "The referee did a big mistake. Clear penalty with the result 0-0 and obviously with influence in the result."
Everton were the next team to profit from a porous defence, as Steven Naismith netted a hat-trick in a 3-1 win at Goodison Park, and Mourinho began to accept that confidence was uncharacteristically low in his squad.
He told BT Sport: "Confidence is fundamental and at the moment everything is going against us. The players fight, play, try, like they did, but the reality is that at the moment it's difficult for them. It's not easy to play football with the confidence level low."
Mourinho finally criticised his charges in the 2-2 draw with Newcastle United by claiming that their first-half display warranted a "minus one out of 10" before the wheels came off in spectacular fashion in the 3-1 defeat to Southampton on October.
Speaking to Sky Sports after the defeat to the Saints at Stamford Bridge, Mourinho raged at what he viewed as a clear conspiracy against his side in a seven-minute rant.
A 2-0 win at home to struggling Aston Villa brought brief respite for Mourinho and his embattled squad, but a game against another claret-clad side last weekend saw it all come tumbling down once again for the former Inter Milan and Real Madrid coach.
Mourinho was sent to the stands as his side slipped to a 2-1 defeat to West Ham United, and a furious Mourinho refused to speak to the press after the game, after perhaps finally failing to reach for a fresh excuse.
League Cup progress aside, Mourinho faces a tricky test against Jurgen Klopp's Liverpool on Saturday, with reports from The Mirror suggesting that the Chelsea manager is on the brink.
Mourinho's past achievements have quite rightly afforded him a considerable level of breathing space, but it is time he ditched the excuses and reminded us all why he is arguably the game's elite manager.
