Real Madrid hit a new low under beleaguered coach Julen Lopetegui as they set an unwelcome club record of 465 minutes without scoring during their La Liga game against Levante as their long search for a goal continued.
Los Blancos are now on a five-game winless run in all competitions, losing four times in the process.
But it took some time for the breakthrough, Marcelo lashing in a right-footed 15-yard strike after Benzema's assist.
Levante should have made it three at the death, Morales firing wide when clean through, before the final whistle was greeted by boos from the home fans.
Real have now gone five games without a win in all competitions, losing to Levante, Alaves, CSKA Moscow and Sevilla, as well as drawing with city rivals Atletico.

Lopetegui's future is now hanging by a thread and it isn't being ruled out that he doesn't even take charge against Viktoria Plzen in the Champions League on Tuesday night.
Although the fact that a Clasico against Barcelona comes so quickly plays into his favour, the hierarchy could be in favour of forcing a reaction as quickly as possible and not compromising their qualification from the Champions League group stage.
Also helped by his woodwork which Madrid struck three times, Olazabal made 11 saves, his best being a close-range block with his leg on Vazquez just before the break.
A four-time Champions League victor, Madrid have come to rely on Varane.
Real Madrid broke their previous record of 464 minutes without a goal in all competitions during a frustrating clash with Levante. "We had 33 shots and not one ball went in", Marcelo said of the game.
Despite being only 12 matches into his tenure, Lopetegui is on course to face the repercussions of the latter scenario.
