Cristiano Ronaldo hit a hat-trick to see Juve win 3-0 tonight and defeat Atletico 3-2 on aggregate.
Griezmann said: “We didn't play the game we wanted to, it was a bad night and we made it easier for Juventus.
“We are all disappointed, as we just didn't play. I'm the first to say I didn't do enough, our tempo was wrong and Juventus were superior on every level.
“Considering we won the first leg 2-0, we can't say much. I don't know what happened, it reminded me a little of the Bayern Munich game, but that time we were able to make some adjustments.
“Tonight, Juve were superior on all levels."
