Raphinha equalised for Barcelona in El Clásico at Spotify Camp Nou after Kylian Mbappé had put Real Madrid ahead.
Mbappé's goal came after Gerard Martín cleared a long ball from Bernardo Silva. The ball reached the forward, who pushed it into the net, and all 11 Real Madrid players touched the ball in the move. Barcelona levelled after a quickly taken corner.
Pedri fed Raphinha, who cut inside and struck low to beat Andrey Lunin. The goal took Raphinha to 15 for the season and 13 in LaLiga.
Lunin started in goal for Real Madrid because Thibaut Courtois was ruled out with a bout of flu and didn't travel to Barcelona. Madrid's defence was Cucurella, Huijsen, Konaté and Valverde, with Bellingham, Bernardo Silva, Tchouaméni and Güler behind Diomande and Mbappé.
Barcelona started with Joan García in goal, Cubarsí and Gerard Martín at centre-back and Xavi Espart and Joao Cancelo on the flanks. Pedri, Rodri and Fermín played in midfield behind Lamine Yamal, Raphinha and Gordon. Barcelona went into the match six points clear of Real Madrid, who were third in the table.
"In a Clásico there are no favourites, but I have good feelings. We are ready," Barcelona coach Hansi Flick said. Mourinho said: "Barcelona are an advanced product and we have only been together two months."
The attendance was 62,055, almost 300 more than the Clásico last May. Mbappé is closing on 100 goals for Real Madrid, a mark Cristiano Ronaldo reached in 105 matches.
