The Frenchman moved to the Blues from Bolton in a £15m transfer in January but has found it difficult to establish himself as first choice in the side.
But Anelka insists he is planning to stay for a long time to come. "I am already very happy to have signed for a club like Chelsea. I have been waiting for that since my departure from Liverpool six years ago," Anelka told L'Equipe. "Even if I don't always play in the centre that is not so serious. With the number of matches we are playing, there has not been a lot of time to work on my partnership with Didier Drogba.
"Am I keen to play regularly on the left flank? No of course, especially because I have never played on the left before in England.
"People who have worked with me know my qualities are in the centre and I believe the Chelsea coach knows it.
"He uses me alone on the centre or on the flank, but it is not a big trouble to me so far.
"I will be 32 at the end of my Chelsea contract. If they want to keep me, I will stay.
"Otherwise you never know. I can move to the USA or come back to Paris Saint Germain. It is an option I can't exclude."
