Wladimir Klitschko has promised to use all his experience to give Francesco Pianeta a boxing lesson on Saturday night.
The 37-year-old Ukrainian, who will be looking for his 60th win, puts his WBA, IBF and WBO heavyweight titles on the line against his 28-year-old opponent at the SAP Arena in Mannheim, Germany.
Klitschko goes into the bout as a huge favourite against the man he used to spar against but insists he will not be underestimating the Italian.
"I don't want to and I won't underestimate Francesco Pianeta," Klitschko told a press conference. "I have prepared how I should, because I know what to expect.
"He's a young chap who, of course, doesn't know his limits. They have to be shown to him in the ring.
"He's very ambitious I understand. I was in the same skin and this is familiar to me, and therefore what is in his head and in his team's is that this is the chance of his life, and of course he'll give everything to win this fight.
"This is familiar to me and, as I've already said, I have been through this and seen it in others who have fought against me. They see the weaknesses in themselves, and I wish them luck with that."
He added: "I know that Francesco Pianeta will have a fight plan but there is the quote by Mike Tyson that says: 'Everyone has a plan until he gets hit'.
"Pianeta will be super motivated and wants to use his big chance but I am very experienced and will show him his limits."
Pianeta comes into the bout with an unbeaten record from 29 fights and is hopeful of using his sparring experience to catch Klitschko out.
"I know him from inside the ring," he said.
"Together with my coach Dirk Dzemski we have a tactic to draw Wladimir out of his comfort zone. Then he's vulnerable."
