Premier League leaders Chelsea maintained their unbeaten start to the season but were made to battle for victory against Crystal Palace.
A brilliant Oscar free-kick and an equally impressive Cesc Fabregas strike ensured Jose Mourinho's men move five points clear of second-placed Manchester City.
Fraizer Campbell scored late on to give the hosts a deserved reward for their spirited performance against a team which dominated possession and territory throughout.
Both teams were forced to play the second half with 10 men as Chelsea's Cesar Azpilicueta and Palace's Damien Delaney were dismissed in two separate incidents.
Azpilicueta was the first to see red, the defender punished for a late two-footed challenge on Mile Jedinak in the 40th minute. Three minutes later, Delaney received his second yellow card for a clumsy challenge on Loic Remy.
Palace boss Neil Warnock remonstrated with referee Craig Pawson at half-time as the pair walked towards the tunnel and the Yorkshireman's ire had not quelled at the final whistle.
Chelsea coped the better with reduced personnel, masterfully retaining possession as Fabregas and Oscar dictated play. At times, the second half resembled a training ground exercise.
In the first half, Campbell's pace had posed the Chelsea defence problems, but the hosts' threat diminished after Delaney's dismissal and hopes of recording a second successive league victory over the Blues receded once Fabregas doubled Chelsea's advantage.
It was a 1-0 defeat at Palace in March which derailed Chelsea's title challenge last season, but Jose Mourinho has said he has since learned his lesson and the statistics back up his argument.
The Blues have won nine and drawn two of their last 11 league matches and even without Diego Costa - the Premier League leading scorer was injured while on international duty - they posed enough of a threat to see off Palace.
