The Italians beat Germany 2-1 on Thursday and have a day less than the Spaniards, who beat Portugal on Wednesday, to get ready for the clash at Kiev's Olympic Stadium.
"I hope to be able to prepare in the best way possible for the match even if we only have a day to get ready," Prandelli told a news conference on Friday.
"We will look for Spain's weak points and work on those areas, even if it won't be easy because they are the world and European champions and here they are in the final again.
"That shows that their qualities aren't just in terms of technique but also on the level of morale and character. They are a reference point in many different ways but we have also improved with time.
"I've always said that my quality of life has improved a lot but in the last two months it has been a struggle, aside from the excellent rapport I have with the team and with the federation," he said.
"They have been two tough months and so there hasn't been the serenity that I look for."
Asked whether those words meant he would be leaving the job after the tournament, Prandelli said, "I was just talking about my quality of life, later I will make my evaluation but I don't want to talk about that now, we will deal with that in three days time," he said.
