David Haye believes that George Groves will benefit from knowing that he is a "world-class" boxer ahead of the eagerly-anticipated rematch with Carl Froch.
The pair will face each other once again on May 31 following Froch's controversial ninth-round stoppage of Groves back in November.
Speaking to Sky Sports News, Haye accused the Nottingham-born fighter of underestimating the Londoner last time out, but says that Froch will be better prepared for Wembley.
"George 100% knows [his ability], before he thought it but didn't know it. Now he knows he's world class and that gives you that advantage going into the second one," said Haye.
"For Carl, he didn't take George seriously, he didn't believe he was world class. I know it, he pretty much told me that.
"But he knows now. So now he's going to be preparing for a world class opponent, mentally."
Earlier this month, Froch claimed that he would "probably retire" if he loses.
