Nobody at the Camp Nou will encourage you to speak or speculate about the "Double Treble."
At the head of this Barcelona squad is a guy in Luis Enrique, whose staff includes a sports psychologist called Joaquin Valdes, who helps the manager prepare him for pre- and post-match press conferences so that the right phrases are used and the right tone set -- so that traps are avoided.
"Lucho" won't play ball if you ask him about the motivational effect that the prospect of winning La Liga, the Champions League and Copa del Rey is having. But it's something that exists, consciously and subconsciously, across every single key member of his squad.
