Arsenal captain Cesc Fabregas hailed his team as 'fantastic' after they defeated defending Premier League champions Chelsea 3-1 at the Emirates Stadium on Monday to regain second place on the league table.
Victory saw Arsenal move to within two points of leaders Manchester United and go second on goal difference above Manchester City. But Chelsea's fifth league defeat of the season left the fourth-placed Blues six points adrift of United, having played one game more.
Fabregas, who scored Arsenal's second goal in between strikes from Alex Song and Theo Walcott, was in no doubt as to how the Gunners had won for the first time in 12 games against Chelsea and United.
"Belief was the difference," Fabregas told Sky Sports 1 after the match. "The difference between a good team and a great team is very little. We did what a great team does. We were fantastic."
Song gave Arsenal the lead shortly before half-time. The hosts then scored two goals in three minutes early in the second period from Fabregas and Walcott, who created chances for one another, after Chelsea were twice caught in possession. However, Branislav Ivanovic pulled one back for Chelsea when he headed in Didier Drogba's free-kick in the 57th minute.
"The league is so tight," the Spain international added. "Anyone can win it. We will try to do our best."
Chelsea boss Carlo Ancelotti, meanwhile, urged his side to "wake up" after a sixth game without a win but added he was "confident" about his own future.
"The difference was the quality," Ancelotti said. "Arsenal put more quality on the pitch than us. They were able to play with the football. They played better than us."
"We didn't play well. We're in a difficult moment. We need to try and win the game against Bolton (on Wednesday).
"The table is not good but this is the reality. We have to wake up. Now we are sleeping," said Ancelotti.
Asked if he was worried this loss would lead to the sack from Chelsea's billionaire Russian owner Roman Abramovich, added: "This is a question you have to ask the owner. I'm confident."
