Chelsea began their Premier League title defence with a thrilling 2-2 draw against Swansea, as Thibaut Courtois was sent off and will now miss the crunch clash with Manchester City.
The Blues were lucky not to go behind early on as Bafetimbi Gomis was through on goal, but fluffed his lines and failed to score. Diego Costa thought he should have had a penalty, but referee Michjael Oliver did not blow his whistle. However, soon after Chelsea were ahead.
A free kick out wide saw Oscar curl the ball into the area and it evaded everyone, including goalkeeper Lukasz Fabianski.
Swansea rallied and came back into the game as Jefferson Montero got away and swung in a wonderful cross; Gomis headed it back across goal but Courtois parried only for Andre Ayew to control and slot home past the despairing John Terry.
The scores were level just a few minutes though, as Willian's shot from a tight angle looped over Fabianski and into the far corner to make it 2-1 at the break.
Ten minutes into the second half, the game turned on its head. A long ball over the top saw Gomis onside -- with Willian playing him on -- and Courtois rushed out of his goal to bring down the Frenchman. The referee adjudged the foul had taken place in the box and the Belgian goalkeeper was sent off and a penalty awarded.
Gomis picked himself up and slotted past Asmir Begovic to make it 2-2, with Oscar taken off and the Blues down to 10 men.
The striker almost netted the winner, but his effort was ruled out for offside, and neither team could find a way to grab another goal.
Swansea had been first to threaten, with Gomis heading wide and then being denied by a late John Terry block.
Diego Costa was infuriated by Michael Oliver's decision not to award a penalty against Fernandez, before an already entertaining, end-to-end contest burst into life with three goals in seven minutes.
With 23 minutes on the clock, Chelsea struck the first blow as Oscar curled in a free-kick that evaded those in the box and nestled in the far corner.
Courtois saved well from Gomis, only for the ball to run free and, having seen his initial follow-up blocked, Ayew showed exceptional awareness to drag the ball back and rifle home.
It was a memorable introduction but one cancelled out inside 100 seconds as Willian's cross-shot looped in off Fernandez.
Costa and Gylfi Sigurdsson tried their luck as the first half continued, with Gomis denied from close range as Swansea returned strongly after the break.
Gomis, put through on goal by Jonjo Shelvey, was halted by a clumsy Courtois challenge, earning Swansea a penalty and the goalkeeper a red card.
Terry was booked for protesting and summer signing Asmir Begovic's first moment in a Chelsea shirt involved him picking the ball out of the net as Gomis coolly slotted home.
Monk's side did not stop there and Jefferson Montero forced Begovic into two fine saves, before Shelvey tried his luck direct from a corner.
Swansea fans celebrated wildly as Gomis turned in their third -- only to be rightly chalked off for offside -- before Wayne Routledge, on for the injured Montero, forced another save from Begovic.
After Eden Hazard and Radamel Falcao had gone close Costa punched the deck in frustration having felt the excellent Ashley Williams had clipped him just outside the box -- frustration that summed up Chelsea's afternoon.
