Chelsea interim manager Guus Hiddink was delighted after his side battled past Arsenal to take three very important points from the Emirates Stadium.
The Blues were underdogs coming into the game but were in control in the early stages and dominated after Arsenal defender Per Mertesacker was sent off in the 18th minute of the game.
Hiddink's men moved up to 13th in the table as they continue their improbable quest to finish in the Top Four.
"Today the boys did their job very well," Hiddink is quoted as saying by BBC Sport.
"We tried to play as much as possible to stop them playing.
"You can react when a team loses a player by bringing on a striker but this Arsenal team are strong and they can outplay you even with 10. It was important to keep structure in the team.
"We had some very good attacks before the red card, Willian had a couple of good opportunities. The red card makes it a bit easier but Arsenal can play well with a man down.
"I like the team playing how they did today, regardless of the gap between here and fourth place.
"We still have two cups at stake. We were unbeaten in seven before this but it was not satisfying because a lot were draws.
"I hope we have made the first step to being unbeaten with pride."
