Antoine Griezmann spoke to the media after Barcelona's 3-0 loss to Juventus in the Champions League on Tuesday, which cost them top spot in the group.
The Frenchman said: "We didn't turn up. In the first half, they were all over us. We lacked everything: desire, attitude, wanting to run, to defend... everything was bad."
And he blamed the players: "It's our fault, we're the ones playing. We have to want to work hard and want to play. We have to want everything. That's the only way to move forward."
Griezmann feels it's time to step up: "We can look for excused but it's time to leave that to one side and work hard, because the image created day is very ugly."
