Anelka is in hot water over his goal celebration on Saturday against West Ham United.
Berahino said: "He has been great. All his advice has been brilliant.
"He is a quiet guy, a good guy. People just look up to him because he leads by example and off the pitch he looks after himself.
"He is 34 but his body is in great shape. He is really humble - you'd never know he has been at all these great clubs.
"He keeps himself to himself and is not one of those lads to show off, so everyone gets on with him."
