Arsenal boss Arsene Wenger couldn't hide his delight following the 5-3 win at Stamford Bridge on Saturday.
The Gunners came out on top in a classic encounter against Chelsea, with the balance of power swinging both ways in the match before Wenger's side took control in the closing stages of the match.
It was Dutch striker Robin Van Persie who stole the headlines, scoring a hat-trick for Arsenal, but the performances of Aaron Ramsey and Laurent Koscielny also drew praise from the Frenchman.
"He is of course on fire and he takes advantage through his class. We attack a lot and we create chances overall of course. The intelligence of his movement around the box and the accuracy of his finishing is exceptional," said Wenger post-match.
"Koscielny was outstanding. He was the one at the back in the first half who looked strong, but I felt we gave them too much room at the back and in midfield and in the second half we got much tighter.
"We kept being dangerous going forward but we were less in trouble defensively. What people forget about players like Ramsey is that he is still young, a top quality player and it is normal that he will improve."
The Gunners are currently on a fantastic run of form, winning eight of their last nine games in all competitions after the worst start to a league season in over 50 years.
Earlier in the week, Wenger told fans things weren't as bad as the British press had suggested, and the victory in west London goes some way to vindicating his comments.
"It's the best habit in my job. We are more consistent now and we have to keep that going now. Tuesday night will be another test where we will have to focus and produce that quality again, that's what is at stake."
