Carl Froch believes that George Groves will be out of his depth when they clash on Saturday evening.
Froch meets Groves at the Phones 4U arena this weekend, and 'The Cobra' thinks that the undefeated Londoner will struggle to match him on the night.
"Make no mistake, the days and hours before going into the ring can be stressful for any boxer, the bigger and tougher the fight the greater stress," Froch told the Daily Mail.
"But if a boxer knows he's stepping out of his league it's even worse. George is in that position and I doubt if he's sleeping much now.
"The closer it gets to fight night the more George will be hating himself. Hating himself for getting himself into this predicament."
Froch overcame Mikkel Kessler in his last fight in May.
