Madrid boss Zinedine Zidane was without a host of first team regulars as the suspended Dani Carvajal and Sergio Ramos joined the injured Marcelo, Luka Modric, Gareth Bale and Karim Benzema on the sidelines.
However, Ronaldo started despite causing controversy with an outburst claiming Madrid “would be top” of the league if his teammates matched his standards after defeat to Atletico at the weekend.
“When there are changes you think it is going to be more difficult, but with the effort and commitment of everyone we managed to get the three points and a good performance,” said Madrid boss Zinedine Zidane.
Real had former Levante ‘keeper Keylor Navas to thank for not getting off to a terrible start as he produced a brilliant save low to his left to prevent Giuseppe Rossi giving the home side a shock lead.
Ronaldo opened the scoring from the spot on 34 minutes after Lucas Vazquez had been tripped inside the area by Lucas Orban.
Injuries to Benzema and Bale opened the door for 18-year-old Borja Mayoral to get his first league start and he took his opportunity when his shot from the edge of the box hit the post and cannoned into the net off Marino’s back three minutes later.
However, Levante were back in the game instantly as the Real defence were caught flat-footed appealing for an offside flag that never arrived and Deyverson slotted into the bottom corner.
Madrid had much better control of the game after the break and Ronaldo was desperately unlucky not to restore their two-goal lead when he struck the post from James Rodriguez’s fine through ball.
However, Zidane’s men needed to rely on Navas once more to secure the points as he made a flying save to parry Ruben Garcia’s shot from distance.
And Isco answered his recent critics with a calm finish from Ronaldo’s cut-back in stoppage time to round off the scoring.
