Sergio Ramos has said Real Madrid's players "are hurting" after their limp 1-0 away defeat to Granada - their fifth league defea of the season.
Cristiano Ronaldo's own goal left Jose Mourinho's side 16 points adrift of Barcelona in the table and seven behind second placed Atletico Madrid.
Mourinho was again critical of his players after a performance in which they looked lethargic throughout and created very few chances.
And Ramos took to Twitter on Sunday to tell fans the defeat had hurt Madrid's players more than anyone else.
"All Madridistas are hurting," he wrote. "The first are we the players. But we will not give up on anything, for our badge and our fans. Hala Madrid!"
At Saturday's post-game press conference in Los Carmenes, Mourinho hit out at those who had not played the full 90 minutes in the 1-1 Copa del Rey draw against Barcelona on Wednesday - including Ramos, Angel Di Maria, Fabio Coentrao, Luka Modric and Gonzalo Higuain - saying they had no excuse.
He also claimed he fixture list favoured Barcelona, adding: "Wednesday was an important match and a tremendous physical effort for both teams, but one plays today and the other tomorrow.
"But this team had to respond in a different manner. Some of the players who played today played on Wednesday, and others did not.
"There are some of them who were tired because [they] worked hard on Wednesday and there are others that I do not know why they were tired, because they were on the bench or in the stands."
There is not much prospect of rest for Madrid's squad this week, with ten players on friendly international duty.
However, Xabi Alonso is out of Spain's friendly against Uruguay in Qatar with a groin problem, while Raphael Varane misses France's game against Germany with a hamstring strain.
Alonso is expected to be back for Sunday's La Liga clash with Sevilla at the Bernabeu. Varane is a doubt for that game, but should be fine for the Champions League last 16 first leg at home Manchester United the following Wednesday.
