The boss wants his players to develop a more ruthless streak and to start scoring some of the easy chances they've been missing, beginning against Everton this Saturday.
"You have to keep analysing the big picture. If every week you think it is one step forward then one step back, you will become very nervous," said Benitez.
"So it is important to keep a perspective and giving confidence to the players. We have just had another win [against Bolton] and another clean sheet. That is a positive.
"Okay, it wasn't as good in attack as we want it to be but we have to keep pushing and we know can improve. We need more positives than negatives.
"The players know that we are improving. We are doing much better in defence and that is a big difference but we have to improve in attack - that is clear."
