Despite maintaining a top-two position throughout the campaign and reaching the Champions League quarter-finals, the club's fans have greeted their recent displays with jeers, with Gareth Bale one player who has been specifically targeted after a poor contribution in recent weeks.
Ancelotti has been backed by the club's hierarchy, but just 10 points from six league games have seen Real overtaken by Barcelona in the league table.
Marcelo is likely to return at left-back in place of Fabio Coentrao, but Luka Modric is expected to remain on the substitutes' bench, despite making a successful return from a long-term thigh problem in midweek.
After a disappointing campaign, Levante have moved themselves out of the relegation zone in recent weeks with three victories from five matches.
Their recent triumphs have come against relegation rivals Granada and Eibar, and Lucas Alcaraz will be delighted with their response after going nine games without a win during the middle stages of the season.
However, all of their recent success has come at Ciutat de Valencia, with their last success on the road coming on September 24, a run spanning 10 matches.
