Arsenal suffered a shock 3-1 defeat at the hands of the league leaders which further dented their title aspirations. [Neville slams Arsenal fans for criticising Wenger]
Marcos Alonso, Eden Hazard and former Gunners star Cesc Fabregas were on target to guide Chelsea to smooth win over the city rivals. Olivier Giroud scored a consolation in the 90th minute.
The defeat against Chelsea drifted Arsenal away from the title as they stand shakily in the third position in the league table 12 points behind the Blues.
Post-match, manager Arsene Wenger drew stern criticism from various sections of the fan base as well as the experts.
Now one of the most experienced players in the Arsenal squad and Arsene Wenger's compatriot Laurent Koscielny has taken a sly dig on his team selection against Chelsea.
The Mirror quoted Koscielny: "I think we played some players in front of others and I think we should have played more as a team and there was space to do so. They hit us on the counter.
"It will be difficult now. Mathematically, nothing is done but we know that it is going to be very complicated. We need to come back to the quality of our game, our passing, movement."
Arsenal take on Hull City in game week 25 next Saturday, February 11 in a must win encounter. Another slip up will completely shatter their dream of winning the league.
