France winger Malouda, 32, has been forced to train with the reserves and youth teams this season - as Anelka was last year before his January move to Shanghai.
"At Chelsea, as soon as you get past 30, you get the impression you're too old," said Anelka.
"It's sad what's happening to Flo. Two years ago, he was named player of the year.
"Chelsea could react in another way. When they need you, you're the best. When they don't, get lost."
