Didier Drogba reckons Chelsea, with victories over all three of their traditional rivals this season, without conceding, shows Carlo Ancelotti's men have the making of champions. The Blues restored their advantage over Manchester United to five points with an impressive 3-0 win at Arsenal.
"Arsenal played their game, but we were stronger than them," said the Ivory Coast international, who now has 10 goals in 11 games against the Gunners.
"Every time we had the chance to score we did. We took our chances.
"Physically we defended well and were really strong, mentally as well.
"I don't know about Arsenal, but it is our strength to perform when it matters.
"Even against Manchester United, when the game was really difficult, we won.
"We know how to go through difficult periods when the game is hard.
"That is why when we get a chance we know how important it is to score."
Despite confidence in his team-mates, the 31 year old knows full well the battle for the championship is not yet won.
"The lead is not enough, but at the same time it's a good gap. We have to keep winning our games," said Drogba, one of several Chelsea players who will be away at the African Nations Cup during January.
"When you are top of the league, it is good - the others have to chase us. They have to produce and do more than us to win games.
"It is true that Manchester are still there.
"We were in their position last year, behind and chasing.
"It is very difficult and now they have to come and catch us.
"I hope we have the team to stay ahead for the rest of the season."
