George Groves has named WBC and WBA super-middleweight champion Andre Ward as the only fighter in his weight class that he would not challenge.
The 24-year-old's trainer Adam Booth claims that the Commonwealth title holder is confident he could defeat any other contender besides Ward.
"The only person he says he can't beat yet is Andre Ward," Booth told ESPN.
"That's the only one that George says, 'At the moment I wouldn't challenge Ward but I'll beat the rest of them.' I keep saying, 'Alright George, let's work on this, let's work on this.'
"He's done so much in the last few months that I am now struggling to justify to myself a reason now to hold him back - not to just let go of the reins and see what he can do."
Groves has been named as chief support for Carl Froch's clash with Mikkel Kessler on May 25, but his opponent has yet to be selected.
