The rematch with Peter (34-3, 27 KOs) is an intriguing one because of their first fight. Klitschko was only in his third fight since being knocked out by Lamon Brewster in a title bout a year earlier and there were many questions about his toughness and how he would react when opposing a fearsome puncher such as Peter.

Peter floored Klitschko three times, but Klitschko kept himself together and won every round in which he didn't go down to take the decision and earn the IBF mandatory title shot. Seven months later, Klitschko knocked out Chris Byrd to win the belt and has held it since.

"Wladimir and myself think the Peter fight is a great matchup," Boente said. "It's a rematch of a good fight. There are a lot of people more interested in that fight than the Povetkin fight."

Peter is already training in Big Bear, Calif., and manager Ivaylo Gotzev said they are eager for another opportunity against Klitschko, especially after Peter had such a poor performance when he lost his version of the title in an eighth-round TKO loss to Vitali Klitschko, Wladimir's brother, in Germany in 2008.

"The IBF has done the right thing and we are negotiating a deal. I expect it to go a lot smoother and a lot quicker than the previous negotiation Klitschko had with Povetkin because we actually want the fight," Gotzev said. "This is a very big fight for the German population and we're going to make it a very big fight for the heavyweight fans around the world.

"You have an exciting matchup that has already proven to be a competitive one. I still get people asking me how Samuel lost when he knocked the guy down three times. We are going to finish what we started in September 2005. This year, it will be a September to remember."

After losing a decision to Eddie Chambers following his loss to Vitali Klitschko, Peter has won four fights in a row, all by knockout, including a second-round knockout of Nagy Aguilera in an elimination bout in March.
