Froch and Groves will meet in their rematch at Wembley on Saturday evening, and Kessler admits that the prospect of stepping back into the ring to face either fighter is an attractive option.
The Dane has clashed with Froch twice - winning the first bout before suffering defeat in the rematch last May - but he believes that Groves has also earned the right to be considered as a potential rival.
"We have to see what will happen on Saturday," Kessler told Sky Sports News. "Of course I want to fight both of them. I think they are great fighters.
"I know Groves has not had a lot of World Championship fights, but what he's shown us the last time is he's one of the big ones now. That's for sure."
Kessler has lost just three of his 49 professional fights.
