Abraham believes that Groves showed his quality when he beat Baker Barakat in March and claims that the 23-year-old could take the WBA and IBF super-middleweight belts from Froch.
"I see Groves as a lively underdog and would not be surprised if he beats Froch," he told Sky Sports News.
"I was ringside March 23, when he stopped his opponent in fashion and I am really impressed by him. He could well be one of the best in the future as he is still very young."
Abraham lost to Froch on points in 2011.
