Arsenal's Premier League title ambitions are well and truly over after the Gunners suffered a humiliating 6-0 defeat to Chelsea in Arsene Wenger's 1000th game in charge. The Pensioners, on the other hand, are most definitely title contenders after this one-sided display.
Jose Mourinho's Pensioners inflicted their game upon the Gunners from the very first moment, as they picked up their biggest ever win under the Portuguese.
Chelsea scored twice in the opening seven minutes through Samuel Eto'o and Andre Schurrle before Kieran Gibbs received a red card to leave Arsenal needing miracles. The Blues continued their rampant first half display as Eden Hazard scored from the spot before little Oscar made it 4-0.
The Brazilian then added his second before recent-signing Mohamed Salah added the embarrassing sixth.
Arsenal have now played away to Liverpool, Manchester City and Chelsea this season and have conceded as many goals against these three teams as the rest combined. Importantly, Wenger has never beaten Mourinho in 11 attempts.
The game started at a frantic pace, with sides tearing into each other right from the off, but it was Chelsea who drew early blood. Mere moments before Eto'o opened the scoring with his clever finish, Olivier Giroud had forced Petr Cech to make an excellent save as the game moved from end-to-end.
Wenger and his team barely had time to breath before Schurrle buried Chelsea's second. Arsenal's 'keeper Wojciech Szczesny was rooted firmly to the spot and could only look on as a spectator as the German international's shot fizzed into the back of the net.
From there, things went from bad to worse for the bedraggled Gunners. Eto'o left the field with a hamstring injury, but he was replaced by Fernando Torres. The Spaniard was instrumental in winning a penalty that resulted in Kieran Gibbs wrongly receiving a red card.
There is no doubt that giving the penalty was the right decision by Andre Marriner, the referee. However, Alex Oxlade-Chamberlain handled the ball on the line, not Gibbs, and should have been sent off in his place.
It mattered little to Hazard who absolutely buried his spot kick to give Chelsea an unassailable lead.
Despite the controversy, the sending off made little difference to the flow of the game, as Mourinho's team were in such utter command.
To add insult to injury, Chelsea added a fourth when the influential Oscar finished with aplomb.
Arsenal reorganized at half-time in an effort at damage limitation. Chelsea, however, goaded on by Mourinho, played in a professional manner and added another two goals to inflict an embarrassing defeat on Wenger in his 1000th game in charge.
In the build up to the game, Wenger told the awaiting media, as per the Independent, that every defeat leaves "a scar in your heart that you never forget."
One thing is for sure, he will never forget this defeat.
