Sergio Ramos scored the decisive penalty when Real Madrid won 4-1 on penalties against Atletico Madrid and won the Spanish Super Cup.
The Real captain sent Jan Oblak the wrong way after 120 minutes in Saudi Arabia to get the trophy.
Saul Niguez and Thomas Partey missed their penalties for Atletico.
Real Madrid ended the game with 10 players after Federico Valverde was knocked out in extra time for fouls on Alvaro Morata.
The dramatic finale contradicted the largely turbulent encounter at the King Abdullah Sports City Stadium in Jeddah.
Joao Felix had the best opportunity for a quiet first half, but he could only shoot further at the edge of the box after being talented by Ramos.
Real was much more successful at the beginning of the second half. Serbian striker Luka Jovic narrowly missed two Atletico defenders.
Atletico only made it in the 79th minute when Kieran Trippiers found pass Morata, whose volley was parried from the edge of the six-yard penalty area by Thibaut Courtois.
The main flashpoint of the game was the remaining five minutes of extra time when Valverde Morata cynically chopped just outside the box when he cleared the gate and triggered a hand-to-hand fight in which both players took part.
In the penalty shoot-out, Saul hit the post with a penalty before Courtois saved Thomas's shot and Ramos secured Real's 11th Spanish Super Cup win.
The tournament had a new format this season: the top two in the league and the finalists in the Copa del Rey played in a four-team competition instead of the two winners competing against each other.
Real qualified despite the third place in the La Liga that Barcelona won the league and finished second in the cup.
