The Dutchman is struggling for goalscoring form this season.
Hughton said: "We know Ricky is a goalscorer but sometimes it takes time. He is the type of player who needs help from his team mates to create chances. What you can't fault with him is his work-rate for the team. We have to give him enough decent service to score goals, but the other side of his game and his work for the team is excellent."
