Two of the six on Saturday were set up directly by the perceptiveness of Anelka, and it is often his clever running which gives Drogba the space to score.
Former Liverpool and Real Madrid striker Anelka told the Daily Express: "I have changed my role. I used to play as a striker, but at Chelsea I play more behind the striker or on the right of him. And I like to play that way.
"I am not a striker any more, not a centre-forward, as I want to enjoy the game more, be more involved.
"In football you need to be versatile sometimes, because the most important thing is to win games and enjoy your football. I like to be part of the game, touch the ball and even to defend, and I can do this now. Some players have to change their game in their careers. I did, and I like it."
Anelka added: "Chelsea want more now. As a player, I always want more. If we try to do the same or even better, then we will be happy.
"I do not think that by winning the Double we have set our standards too high. Maybe there are now more challengers for the title."
