Chelsea striker Nicolas Anelka admits he's been frustrated by wrong offside calls since joining in January.

"I think maybe it has happened more in Chelsea," he told the club's website. "I don't know why but when the referee says it is offside, it is too late to do anything about it so I have to deal with it. But I hope this changes.

"It is my game and I've always played like that. Even sometime when someone gives me the ball in the right moment and I am not offside, maybe someone thinks I am because I am soon four or five yards in front of the defenders. But that is life, I will never stop playing this way, this is my game and I am waiting for the right decision."
