The experienced playmaker is eagerly anticipating Tuesday's away game and has little doubt that Juve will be up for the challenge
The Scottish giants surprisingly beat Barcelona at home earlier this season, but Pirlo has stressed that Juve will not make the same mistakes the Catalans made as he believes the Bianconeri will be ready for anything Celtic thrown at them.
"We are ready for anything. We have seen how Celtic beat Barcelona, but maybe we are better prepared than the Catalans on how to adapt to the circumstances," Pirlo told Tuttosport.
"They play some fantastic football, but Celtic frustrated them with their approach. Whatever they will try, Juventus will be ready for it, though.
"If they want to play football, we'll respond by playing football. If they want to fight, we will be ready to go to battle."
Tuesday's first leg at Parkhead kicks off at 20:45CET.
