Real fired in 16 goals in the four matches leading into the winter break, but they have run into a barren patch since their return to action.
A 0-0 draw away to Osasuna, a 2-0 home win over Real Mallorca and last weekend's 1-0 defeat at Athletic Bilbao have seen second-placed Real slip five points behind unbeaten leaders Barcelona.
"We create a lot of chances but we just lack a little luck," Real defender Sergio Ramos told sports daily Marca.
"This should prompt us to be more assured in front of goal and to work hard to improve."
However, a money-spinning midweek friendly in Albania on Wednesday may have helped boost Kaka and Benzema's confidence after both scored in the 2-1 win over Gramozi Erseke.
This weekend's matches usher in the mid-point of the season with Barca already assured of the honorary title of 'winter champions'.
"I have high hopes that we can turn the situation round," the Argentine Gorosito said at his presentation.
"I intend to play with the team a little higher up the pitch than they have been doing, because it is difficult to win without thinking about your opponents goal."
