Atletico Madrid ace Antoine Griezmann says their European Super Cup triumph is proof he was right to stay.

Atletico stunned Real Madrid 4-2 in Tallinn on Wednesday night.

"I stayed because there was a good project, I have confidence in this club, in Cholo ... Today I saw that I was not wrong," said Griezmann.

"It would be the fifth game, the first official, we did a lot of work, a lot of effort ... Those who came on made the difference, we must continue like this because we are a great group."

He added: "I was a little bit drowned because it was my second game."
