The thing about miracles is you don't prepare for them. You don't wait for them. They just happen.
Barcelona will try to make a miracle happen on Wednesday night at Camp Nou when they face PSG looking for a place in the UEFA Champions League quarterfinals. The Catalan giants lost 4-0 in Paris and need five unanswered goals to advance to the next round.
Given the manner in which the Blaugrana lost in France three weeks ago, no one expects Barça to advance. They lost 4-0 and played horrible football while a physical PSG side absolutely destroyed the Catalans in every phase of the game.
