Arsenal lost their unbeaten Premier League record on Sunday as the Gunners suffered a 2-0 defeat at league leaders Chelsea.
The Gunners had the first attempt of the game on three minutes, as Alexis Sanchez fired well wide of goal with a long range effort. On ten minutes Sanchez collided with Chelsea keeper Thibaut Courtois, which led to a slight delay in play, as the Belgium international received treatment.
The game then went through a scrappy period with the biggest talking point handbags between Chelsea boss Jose Mourinho and Arsenal boss Arsene Wenger on the sidelines. The home side were awarded a penalty kick on 26 minutes.
Winger Eden Hazard ran at the Arsenal defence and was fouled by Laurent Koscielny in the penalty area. The Belgium international then stepped-up and sent Wojciech Szczesny the wrong way with the spot kick.
On 28 minutes Chelsea full-back Cesar Azpilicueta attempted an effort from long-range, which was gathered easily by Szczesny. On 30 minutes Arsenal had a chance.
Santi Cazorla ran at the Chelsea defence and played Jack Wilshere in through the Chelsea defence. Unfortunately for the England international his first touch was heavy and Chelsea substitute keeper Petr Cech was quick to get out and gather the ball.
The Gunners posed the first real attacking threat on 49 minutes, as Cazorla fired just wide of goal from just outside the penalty area. Szczesny got slightly lucky on 54 minutes, as his intended clearance hit Chelsea striker Costa and bounced clear to a Gunners defender.
The Gunners came close to conceding a second goal on 58 minutes. Hazard ran at the Gunners defence, his cross hit Mathieu Flamini and Szczesny had to react quickly to knock the ball onto the post.
The game became very scrappy and Chelsea boss Jose Mourinho showed his intent of shutting up shop on 69 minutes by putting defensive midfielder John Obi Mikel on for German winger Andre Schurrle.
Arsenal had an attempt on goal on 73 minutes, as Gunners full-back Calum Chambers fired well over the bar. On 75 minutes it was Chelsea who came forward. This time Diego Costa held the ball up well and found Hazard in the area, who fired over the bar from a tight angle.
The home side doubled their lead on 78 minutes. Former-Gunners midfielder Cesc Fabregas found Costa through the middle of the Gunners defence with a chipped pass and the Spanish lofted the ball over the out-rushing Szczesny and into an empty net.
Gunners substitute Lukas Podolski looked to be in on goal on 90 minutes, but a combination of Gary Cahill and Petr Cech denied the German international. In stoppage-time Costa looked to have missed a golden opportunity to score his brace from a few yards out. The Spaniards blushes were spared by an offside flag.
In the end the Gunners lost their unbeaten Premier League record, as the Blues were too strong for the visitors.
