Real Madrid goalkeeper Keylor Navas says every player is "hurting" after their thrashing by Barcelona.
Navas conceded four goals at home against Barca on Saturday.
"We're all really hurting because of what happened; we're professionals and we're aware that we put in a very bad display. Both the players and the coaching staff take responsibility for their mistakes and we know that there are aspects we have to change if we're to be successful. We're out to fight to achieve the goals that we have in front of us. It's down to us, and over the remainder of the season we want to bounce back," he said.
"We all have to run that bit harder. We're a team, and it isn't a question of some of us running more or less. I have confidence in all of my team-mates. I know the qualities that they have and the type of team that we are. We're a team; when we win, we together, and when we lose, we lose together."
