NEW YORK – Bryant Jennings didn’t divulge details, but he has noticed that Wladimir Klitschko still makes some of the same mistakes he made when he lost to Lamon Brewster and the late Corrie Sanders.

Klitschko’s exploitable flaws are among the things that have left the undefeated contender from Philadelphia confident he call pull off what would be considered a huge upset in their heavyweight title fight Saturday night at Madison Square Garden (HBO). Nevertheless, Jennings (19-0, 10 KOs) realizes the 39-year-old Klitschko (63-3, 53 KOs) has improved considerably since Brewster beat him by fifth-round technical knockout 11 years ago, 13 months after Sanders stopped him in the second round of their March 2003 fight.

“That was years ago and Wladimir has gotten much better,” Jennings, 30, said. “But you definitely pay attention to it and try to figure out things that he has repeated since then – because there are things where you say, ‘Wow! He still does that.’ So you just capitalize on those things.

“You have to watch all of his fights and there was something that was repeated, and it happened all of those times. Now maybe since he hasn’t really been faced with fighters such as those guys, who were really able to get up in there and test those limits, he may have forgotten all about it. And that same little mistake is going to come back to haunt him. It’s up to me to remind him.”
