Chelsea manager Carlo Ancelotti hailed the spirit of his players after their 3-0 demolition at Arsenal.The Blues extended their lead at the Premier League summit by five points thanks to two wonderful Didier Drogba goals and a Thomas Vermaelen own goal. [LNB]"It was a very good performance. If you win 3-0 at Arsenal you have to do a good job," the Italian, 60, said. [LNB]"The defence did a fantastic job, all the players worked for the team," he added saving special praise for Drogba. [LNB][LNB] Great result. We were just simply too strong/powerful for the goonies The-Essienator Chelsea have won 12 in 14 matches in their current Premier League campaign, with Sunday's losers Arsenal now lying 11 points behind their London rivals. [LNB]Striker Drogba opened the scoring with a delightful flick and his stunning curling free-kick followed Vermaelen's unfortunate prod into his own net. [LNB]"Strength is a quality of this team, we have to use this. We have a lot of different qualities, mental as well as physical," added Ancelotti, who also revealed defender Ashley Cole had suffered a slight muscle tear. [LNB]"We wanted to use intelligence to defend our half and there we won the game. Arsenal put a lot of players in midfield and sometimes they lost the balance. [LNB]"Arsenal kept the ball well in the first half but we always had the possibility to score on the counter-attack. We stopped them in midfield. There we won the game."[LNB] [LNB][LNB]Everything went for Chelsea - Wenger[LNB]Regarding his double goal scorer, the Blues boss said: "Drogba has a good spirit - goals are good but the most important thing is working for the team." [LNB]Meanwhile, Arsene Wenger was left furious after referee Andre Marriner ruled Eduardo had been guilty of dangerous play for flicking the ball away from Chelsea keeper Petr Cech before Andrey Arshavin put the ball into the net. [LNB]The score was 2-0 at the time of the incident and with Arsenal still looking dangerous on the break, the Frenchman said: "How can he see Eduardo kicking the ball from Cech when it was a Chelsea player kicking the ball? [LNB]"That was a very important goal in this kind of game and it was big mistake by the referee. [LNB]"What can you say about referees this year? The Chelsea v Manchester United game was clearly decided by the referee (John Terry scored a controversial winner on 8 November). It is important they don't make mistakes in big games. [LNB]"He told me it was dangerous play from our player. He got the turning point of the game wrong. It was not a serious decision."[LNB] [LNB][LNB]Drogba 'feeling good' about form[LNB]It was a decision, though, that did get the support from Ancelotti who said: "Arsenal are upset because they lost and I think it was a foul on Petr Cech." [LNB]Marriner was also in charge of Liverpool's 2-0 win over Manchester United last month when he was accused of struggling with the intimidating Anfield atmosphere by Sir Alex Ferguson. [LNB]Wenger added that Chelsea had been lucky to have achieved such an emphatic result at Emirates on Sunday. [LNB]"The score is a very unfair reflection of the game but it is the score and we cannot change it now," he added. [LNB]"I believe that Chelsea had absolutely everything for them. The first shot on goal they scored and the second cross they scored. And after that it was difficult. [LNB]"They are physically strong players, but that is the impression you get when they are 2-0 up. They just defended in their own half and attacked on the break. [LNB]"They lost many balls and made many technical mistakes but we couldn't take advantage."
