Diego Costa scored twice as Atletico Madrid beat Real Madrid 4-2 in extra time to claim the Super Cup in Estonia.
Costa scored the quickest goal in Super Cup history when he gave Europa Cup winner Atletico the lead inside the first minute.
Karim Benzema levelled for the Champions League winners before a Sergio Ramos penalty put them ahead in the second half - only for Costa to score again to force extra time.
Saul Niguez volleyed Atletico in front in extra time before Koke sealed the victory in the 104th minute as Real started the post-Cristiano Ronaldo era with defeat.
The match, held in Tallinn, Estonia, is Real's first competitive fixture since Ronaldo was allowed to join Juventus in July and the first under new manager Julen Lopetegui.
Diego Godín raises the Super Cup high in the air 🙌

City rivals Atletico, whose coach Diego Simeone is serving a touchline ban, handed a debut to France international Thomas Lemar, but it was former Chelsea man Costa who turned out to be the star.
Costa smashed in the opening goal after just 49 seconds after he chased his own flick-on following Diego Godin's ball forward, held off Sergio Ramos and fired beyond Keylor Navas at the near post.
What a start, what a goal!

Real levelled in the 27th minute through a header from French forward Benzema following good work down the right wing by Gareth Bale - who is looking to fill Ronaldo's boots in Madrid this season.
Real turned the game in their favour with 63 minutes played courtesy of a Ramos penalty. Atletico defender Juanfran, under pressure from Benzema, was penalised for handball, and Real captain Ramos coolly slotted into the bottom right corner from the spot, sending Oblak the wrong way.
Costa claimed his second of the night to bring Atletico level at 2-2 with 11 minutes remaining - tapping in an Angel Correa cross to force the game into extra time.
Atletico went ahead for the second time in the match eight minutes into extra-time.
Substitute Thomas Partey dug out a cross from the left following a pass from Costa and Saul Niguez volleyed powerfully into the top right corner.

Koke then added a fourth goal for Atletico with a neat strike into the bottom corner in the 104th minute.
Atletico held on to seal a 4-2 victory after extra-time against Lopetegui's side.
