Juventus striker Fernando Llorente says they must be at their best against Real Madrid.
Juve meet Real next week in the Champions League semifinal.
Llorente said: "It's hard not to think of a game like the one against Madrid. We'll have to play a perfect match, because they don't make mistakes.
"We can hurt Real, and I'm ready to give everything. We did well against them last year [in the group stage].
"We should have won in Turin, but we compromised that victory with a mistake, but if we don't commit errors we can do it."
