Summer signing Joao Felix proved his worth while Diego came away with a super hat-trick and a red card in a heated Madrid Derby.

Real Madrid and Atletico Madrid locked in what was meant to be an International Champions Cup friendly. However, that was far from the case, as we were treated to a heated derby full of action, goals, and heated clashes.

The two Spanish neighbors locked horns at the MetLife Stadium in what turned out to be a 10-goal thriller, with Simeone's men smashing Los Blancos 7-3 in this pre-season clash. There were even sending offs, with both Diego Costa and Dani Carvajal being shown red cards after an on-the-pitch bust-up.

It might have been just a friendly, but the match brought tons of talking points. Here are the key ones after Los Rojiblancos convincing win over their city rivals.

Diego Costa's four-goal haul food for thought for Simeone

Remember how Diego Costa was being linked with a move to the Premier League a while back? While the rumors hinting at a move to Wolves or Everton have died down, his future at the Wanda Metropolitano remains under doubt. However, after seeing the 30-year-old scored a super hat-trick, with three of those four goals coming in the first half, he might reconsider selling the Spaniard given that their other striker Alvaro Morata is yet to prove himself.

It was a roller coaster performance from Diego Costa 

Griezmann's departure a blessing in disguise after Joao Felix's masterclass?

Joao Felix might have arrived at Atletico a few days before Antoine Griezmann's exit was confirmed, but the Portuguese starlet was brought in as a replacement for the Frenchman. Many began wondering if the Madrid giants could cope with the World Cup winner's transfer to Barcelona but could his exit have been a blessing in disguise?

Felix put on a masterclass performance against Real Madrid in the 7-3 win. He came away with a goal and two assists under his belt and was the driving force behind many of their attacks. Could Costa have scored four goals without the former Benfica man? Probably not, given that he set up two of his goals. The 19-year-old created opportunity after opportunity and should have come away with more assists but his display was enough to impress everyone. Real Madrid's defense could not handle him.

It was an unforgettable 90 minutes for Atletico's star signing 

Speaking of Real Madrid's defense...

The season hasn't even begun but the worries pile on for Zidane

There's no way Zidane watched that performance without worrying about the upcoming season. The manager insisted that he is calm but their defense was nothing short of shambles. It can be blamed on a lack of fitness and intensity that is common with players who have just returned from their summer holiday. But if that's the case, they are already playing catch up with Simeone's men as they appeared more ready for the upcoming season.
