Barcelona coach Ronald Koeman says they're a different team to their defeat to Real Madrid earlier this season.
Asked by Sport about how the team have evolved since the Clasico defeat in October, Koeman took advantage of the question to send a message to his players.
"In certain aspects, the team has improved," he said. "In the period of the first Clasico, the team was good. I remember we were better, above all before half time and had chances to take the lead. We lost the game in the second half, the VAR, the penalty...
"I think we've improved things, but it's not true that we were poor then and now we're much better. We are more effective now and we've improved in defence, the system can also change.
"The team has run into good form, playing with a lot of energy and that's what I ask for tomorrow. Not to go crazy because it's the Clasico or it's Madrid, but to be ourselves. That's the message from me. The opposition are a good team but we have to do things our way, as we have done recently."
