The Ivorian striker has been impressive so far this season, scoring four goals already.
Drogba insists Chelsea need to win the Premier League or Champions League this season.
“I don’t mind which but we have to win one,” Drogba told the Chelsea magazine.
“Why can’t we win both? Every time my fitness is good, I play well and I score goals. People like to say every time I come back to full fitness after injury, ‘Oh this is the new Drogba’. But there’s nothing new, I’m just scoring goals like I did before, I’m the same player.
“Dropping in and connecting midfield and attack like I do when I play with a strike partner is how I played with Marseille.
“And the way I played with Damien Duff and Arjen Robben in my first two seasons here – meeting crosses and attacking balls – is how it was with Guingamp.
“I love to receive the ball into feet to be given the chance to try to create something, to pass to my team-mates and it makes me more unpredictable because I can use my balance and my strength to help.
“My biggest strength and my biggest weakness is my confidence, I know that I can score goals so my confidence is always high. Even if I’m not playing my confidence is high, but then I think about what I could do if I was playing.”
He added: “I feel totally settled here.
“It took me a bit of time in my first season because my oldest kid was not happy to begin with and wanted to move back to Marseilles. Family is really important to me and I wanted to make sure that they were happy as it helps you perform well.
“At home, if someone is happy then they will be happy at work. It came good – my kids started to speak English and we made some friends here.
“The thing is people are always talking about the day I said I wanted to go from here, but I’ve said I’m happy here many times and I am. I have my plan – I know what I want to achieve with Chelsea – and I’m here to stay, and want more success.”
