Inzaghi is confident their defeat to Manchester City two years ago has them better prepared this weekend.
He told TNT: "The match from two years ago will help us. We know we are facing a team with players who have won world championships and many championships in France.
"They are also experts, we will try to play a great game. They are two excellent teams that deserved to be in the final: there will be a huge crowd, two great fan bases."
Asked if Lautaro Martinez can be considered in the running for the Ballon d'Or, Inzaghi also said: "For me, for what he has done in these years, he would always deserve it.
"Regardless of whether we win or lose the match on Saturday. Lautaro is a great player and a great person."
