As well as going through the longest goal drought in their decorated history after failing to score against Levante in the opening ten minutes of the second-half, Real Madrid are now five games without a win after Saturday's 2-1 defeat.
Marco Asensio was the last player to find the net for Los Blancos, when he scored four minutes before half-time in a 1-0 home victory over Espanyol on September 20.
Jose Luis Morales put Levante ahead in the 7th minute, after a defensive slip from Rafael Varane.
The current scoreless run ended 16 minutes later when Marcelo pulled one back.
Real were seeing plenty of the ball after a frantic start and continued to fashion opportunities, with Mariano planting a header against the bar while Lucas Vazquez was denied by a superb save from Levante goalkeeper Oier Olazabal.
Just before half-time, a magnificent Levante passing move, finished off by Ruben Rochina, was then ruled out through VAR due to offside in the build-up. It had been reported that this surpassed a previous record barren run of 464 minutes, set in 1985.
Real host Viktoria Plzen in the Champions League on Tuesday before a crunch game away to arch rivals Barcelona next Sunday and the coach admitted his team need to have a meeting to address their failures in front of goal. It seems that form would continue into the new season after they demolished Real Betis 3-0 at Benito Villarmartin in their first game.
On the other hand, Levante are seventh on the table with 13 points.
In the nine years Ronaldo spent at the Bernabeu, he scored 450 goals in only 438 appearances, including 44 in 44 games last season, suggesting that even at 33, he was losing none of his potency.
