Pierre-Emerick Aubameyang scored twice on his El Clasico debut as Barcelona stunned La Liga leaders Real Madrid 4-0 at the Bernabeu.
Aubameyang headed the visitors in front in the 29th minute and scored their final goal early in the second half.
Ronald Araujo doubled Barca’s advantage before the break, with Ferran Torres adding a third on the counter-attack after 47 minutes.
Real Madrid were seeking a sixth straight win in this fixture, but looked uninspired and created little as their lead over Sevilla at the top remained at nine points.
Xavi’s Barcelona stretched their unbeaten run to 12 games and rose up to third in the table, 12 points behind Real with a game in hand.
Aubameyang adds momentum to Xavi revolution
Barcelona have looked a completely different proposition since Xavi replaced Ronald Koeman in November, only losing once in La Liga in that time – and that defeat was more than three months ago.
Their winter signings from the Premier League have transformed them too, Aubameyang from Arsenal, Torres from Manchester City and Adama Traore from Wolves.
Only Memphis Depay (10 goals) has scored more than Aubameyang (nine) and Torres (five) for Barcelona this season.
It is surely too late for a title challenge, but this landmark result shows Barca are back – and could be in contention for the big trophies next season.
They blew Real Madrid away for their first Clasico win in three years. The impressive Ousmane Dembele set up the opening two goals, headers by Aubameyang and Araujo.
Araujo had been chosen to start at right-back instead of Dani Alves to deal with the threat of Vinicius Jr, but ended up on the scoresheet himself.
Aubameyang set up Torres with a delightful backheel pass and chipped in their fourth himself, a goal initially ruled out for offside but given by the video assistant referee.
They wasted many chances to score more, with Aubameyang and Torres having six shots each.
