Real Madrid boss Zinedine Zidane sees their clash with Eibar as a must-win.
Real are reeling after their Champions League humbling at Wolfsburg in midweek.
"We have to go out strong and be on our game, and not give them any chance. We have to beat Éibar and then we'll think about the Champions League. We must respect our opponents, they are going to come out strong, but we know what we have to do to make the game easier," said Zidane.
“I don't expect a bad reception from the fans, I'm sure they'll be with us. We're playing for our season on Tuesday, we know that, it's an important game and I think the fans enjoy that as well. I like it when things get tough, and I believe the fans do too, on occasions. Nobody expected what happened in the first game but this is football and it's in the past now."
