Real Madrid had a night to forget in the International Champions Cup as they suffered an embarrassing 7-3 defeat to Atletico Madrid, with Diego Costa netting four on the night.
Zinedine Zidane included the likes of Eden Hazard, Isco, Toni Kroos, Luka Modric, Sergio Ramos and new signing Luka Jovic in the starting line-up.
Atletico wasted no time in making their intentions known as Joao Felix slipped in Costa, who sent a fine finish into the bottom corner, leaving the Los Blancos shell-shocked.
Seven minutes later, Felix grabbed his name on the score-sheet after tucking home a cut-back from Saul Niguez for his first goal in the colours of Atletico.
It got worse for Los Blancos after the 20-minute mark, with Angel Correa bagging Atletico's third with a first-time finish before Costa netted his second and his side's fourth on 28 minutes.
There was enough time for Costa to complete his hat-trick just before the halftime break after the striker was brought down in the box for a penalty, which he duly converted to make it 5-0 on the night.
Zinedine Zidane threw on Dani Carvajal, Keylor Navas and Lucas Vazquez at the start of the second half, but it no made difference as Atletico bagged a sixth on 51 minutes through Costa's fourth of the game.
Ten minutes later, Los Blancos managed to open their account as Eden Hazard broke the down left flank before pulling the ball back for Nacho, who poked home from close range,
There was always going to be a scuffle or two in a Madrid derby, although this time two players were sent off as Carvajal was shown a red for a danger challenge on Thomas Lemar while Costa's impressive was ended on 65 minutes as he was sent off for his involvement in the scuffle.
Despite the absence of Costa, Atletico managed to bag a seventh goal with 20 minutes remaining as Vitolo weaved his way into the box before burying the ball into the bottom corner.
There was a late flurry of goals from Los Blancos, with Karim Benzema netting from the penalty spot while Javi Hernandez scored another moments later, but it did nothing to soften the blow of a horror defeat by Zidane's men.
