Enrique has praised the former Liverpool striker for his attitude amid his four-month ban for biting Giorgio Chiellini at the World Cup.
Enrique told reporters: "He is adapting and waiting for his opportunity. He is training as if he could play tomorrow and that was our objective.
"Already, even without playing, I think he is helping us and has been a good signing."
Suarez, who signed for the Nou Camp outfit in July for a reported £75m, could return to action in the El Clasico on October 25.
