Real, who were also knocked out of the UEFA Champions League at the last-16 stage by Ajax Amsterdam, put in the kind of lethargic performance which has plagued their season, with Marco Asensio and Raphael Varane missing good first-half chances.
It meant as Barcelona were preparing to face Manchester United in the Champions League quarter-finals on Tuesday, Real Madrid stepped out looking to salvage only pride and, perhaps, momentum ahead of what most expect to be a busy summer.
Zidane openly admits Real Madrid are 'going to make changes'
Real Madrid manager Zinedine Zidane declared he and his players had a duty to improve after they were held 1-1 at Leganes. Things may be about to get worse for Bale as Vinicius Junior's return from injury in the coming weeks is likely to drop him deeper into the bench.
Leganes, 11th in the table, went close to winning the game but Youssef En-Nesyri had a goal correctly disallowed for offside. "He's a fantastic player and this season he's scoring far more goals".
"The changes will be made known at the end of the season", Zidane said.
He played the full 90 minutes against Celta Vigo and Huesca, but he was replaced against Eibar and came on late at Valencia and Leganes. "We make the changes to win the game, and we did not do that today".
"We have our pride and our love for this shirt, which is worth more than any title", Navas said.
