Barcelona's 4-0 El Clasico victory at Real Madrid will "go down in history", according to coach Luis Enrique.
Luis Suarez scored twice and Neymar and Andres Iniesta also netted as Barca - for whom Lionel Messi was a second-half substitute - went six points clear of Real at the top of La Liga.
"This victory tastes glorious because it is against our eternal rivals," said Enrique, who played for both sides.
"It will be very difficult for us to better this performance."
Barca were as dominant as the scoreline suggests and could have won by more goals.
Enrique added: "Winning like this against players of such a high level is difficult, but we managed to pull off what we were hoping to do throughout the game.
"I don't think Real Madrid gave up. We were a level above them and we outnumbered them in many areas of the game. The game is more of a reflection of our merits than Madrid's faults."
