Herrera said: "We know that it is going to be a very difficult match that is going to require us to be one hundred percent and concentrated for more than ninety minutes.
"We are very motivated, confident that we can achieve something important, but we know that along the way there is a very strong rival led on the bench by Tata (Martino) and on the field by the best in the world (referring to Messi), so for us it is an extra motivation."
