Antoine Griezmann insists Atletico Madrid winning the Super Cup justifies his decision to extend his stay at the Estadio Wanda Metropolitano.

The 27-year-old was a key target for La Liga champions Barcelona, but announced he would stay at Atletico during the World Cup.

The French international produced a mixed performance in Wednesday’s Super Cup win in Tallinn, replaced after 57 minutes as he continues to build up his fitness levels ahead of the new season.

Diego Costa’s superb brace and goals in extra time from Saul Niguez and Koke saw Los Rojiblancos overcome their Madrid rivals.

“I stayed because there was a good project,” Griezmann said to Movistar.

“I have confidence in this club, in Diego (Simeone)… Today I saw that I was not wrong.

“I was a running in water a bit because it was my second game.

“In the end the important thing was to get ahead on the scoreboard, we made a very complete final.

“We know that physically the two teams have not reached 100 per cent, the key was the desire to win.

“It was time for us to win the UEFA Super Cup again, it was very important to start the season like this.”
