Barcelona: Luis Enrique takes blame for Champions League exit

"The team are sad. We aren't at our best at the moment, nor our most effective," he said.

"I'm 99.9% to blame, no 100. That's why I am the coach, the most responsible. We all have to improve."

Antoine Griezmann scored both goals for Atletico at the Vicente Calderon, while Lionel Messi failed to net for the fifth club game in a row.

"It is clear that we are not in our best form, especially if you consider how we were playing before, but we need to lift ourselves," added Enrique.

It is only the third time in 11 years that Barcelona have not reached the semi-finals of the Champions League. Barcelona did not qualify to enter champions league tournament finals.
