Chelsea have moved five points clear at the top of the Premier League table after an impressive 2-0 home win over Arsenal.
The Gunners started the brighter of the two sides, but just couldn't find the breakthrough.
Things went from bad to worse for the hosts as Thibaut Courtois was forced to go off with a head injury. But Petr Cech look assured between the sticks as he made his first Premier League appearance of the season.
Eden Hazard showed a bit of brilliance before the break as he danced through the Arsenal defence, before being brought down for a penalty. The Belgian International dusted himself down to convert the spot kick himself.
And Diego Costa added a second late on to nothch his ninth goal in seven games.
