Bayern go to Turin defending a 2-0 lead for the second-leg of their quarterfinal.
"After the first game we talked over what happened," declared Pirlo.
"It certainly was not a good performance, as we played below our capabilities and they were better than us in that match. However, we have the chance to turn this around. We know it will be difficult, but it is achievable.
"Don't forget I was there in Istanbul when Milan were 3-0 up against Liverpool and we were convinced we'd be lifting the Champions League trophy. It ended 3-3 and we lost on penalties.
"I was there in La Coruna, when after a 4-1 first leg victory we lost 4-0 to Deportivo. We were Milan, not any old team... Therefore, Juventus must be convinced that we can do this."
