Chelsea underlined their title ambitions by brushing aside Arsenal 3-0 at the Emirates Stadium yesterday.

Drogba was on target twice in the win, which was Chelsea's seventh in a row, to move Carlo Ancelotti's side five points clear at the top of the table.

The win all but ended the Gunners' chance of winning the championship and effectively made the title chase a two-horse race between the Blues and Sir Alex Ferguson's side.

The Ivory Coast striker is determined that his side will not lose their focus as the season enters the festive period.

"Yesterday's win just showed that we deserve to be top of the league and I hope we will still be there at the end of the season," Drogba told Press Association Sport.

"But the season is a long way from its finish. There's still a long way to go and Manchester United are only five points behind so we have to fight until the end and we are going to fight all the way to the end of the season."

Drogba arrived at Stamford Bridge in a £24million transfer from Marseille in 2004.

He then went on to win two successive titles under the guidance of then manager Jose Mourinho.

He has since been coached by three managers - Avram Grant, Luiz Felipe Scolari and Guus Hiddink - before Ancelotti took charge following his departure from AC Milan.

The 31-year-old thrived under Mourinho and now believes Ancelotti is beginning to rekindle the kind of team spirit the current Inter Milan boss brought to the Stamford Bridge dressing room.

"At Chelsea, my first two seasons were really good, the team bond was really strong," Drogba said.

"Now this one is a little bit like it was during those years when we were champions under Mourinho."

One big test for Chelsea's title ambitions will come in January when they lose Drogba, Salomon Kalou, John Mikel Obi and Michael Essien for the African Nations Cup.

The Blues had to do without Drogba for their first four Champions League games this season due to suspension and he believes Chelsea have enough strength in depth to cope without their African stars for a month.

"I think the team will be okay without me, of course they will," he added.

"We have a lot of talented players and I've no doubt that they will be able to do the job without me."

Drogba was speaking at the launch of Nike's Red campaign alongside U2 singer Bono.

The pair hope to raise money for HIV/AIDS research by promoting the sale of red football boot laces, which will be worn by footballers sponsored by Nike for the rest of the season.

Drogba pointed to his boot laces when celebrating both of his goals yesterday and he hopes he can raise more awareness about the plight of those affected by the deadly disease through the campaign.

"Yesterday wearing those laces inspired me because I wanted to score so that everyone could understand the scale of the problem," he added.

"It's a very big problem in Africa and one I want to help fight."
