Cristante told reporters: "There is little to be said, we were outplayed from all points of view, we need to clear our heads and understand what we did wrong and start again with a different attitude.
"At the level of organisation there was so much difference and when there is so much difference then the energy is lost, there is nothing to say and we go home deservedly."
He added: "Preparation? I don't know, there are many things that didn't go (well). We played so badly compared to the others and it is therefore down to many factors."
