"We will certainly give it our best shot. We know they are like a tank, but with the desire we showed tonight, the balance can change.
"It was a gritty Juve side. We wanted to win the match and that's exactly what we did. Empoli clammed up in defence, so it was essential for us to break the deadlock."
On Trezeguet, Ranieri added: "David was decisive and I am happy for him," added Ranieri. "He scores goals, comes back to help the midfield and covers his teammates. He is in great shape."
Tiago Mendes got a rare start and impressed with all three assists for Trezeguet.
"I think Tiago played well. He was at the centre of the play and took the team in hand. He has to continue like that."
