Diego Costa scored four goals and was sent off as Atletico Madrid thrashed Real Madrid 7-3 in a pre-season match in New Jersey.
Costa opened the scoring inside the first minute and completed his hat-trick with a 45th-minute penalty.
Joao Felix, a £113m summer signing, also scored his first goal for the club as Atletico led 5-0 at the break.
Costa added his fourth goal six minutes after the restart, before he and Real’s Dani Carvajal were red carded for fighting in the 61st minute.
Angel Correa, on for the injured Alvaro Morata, was also on target in the first half, while Vitolo added Real’s seventh in the 70th minute.
While they were 6-0 down, Real got on the scoresheet through Nacho, while Karim Benzema and Javier Hernandez both scored late on.
Real, who have spent close to £300m this summer, started with new signings Eden Hazard and Luka Jovic.
But they have struggled on their US pre-season tour, losing 3-1 to Bayern Munich and beating Arsenal on penalties after a 2-2 draw.
