Ricky Hatton says a meatier and more mature George Groves is capable of defeating Carl Froch in Saturday's super-middleweight showdown.
Groves, who will try to prise Froch's IBF and WBA straps in Manchester when he enters a world title fight for the first time, has not been shy in questioning the abilities of his more senior opponent.
But Hatton - who stunned Kosta Tszyu in what is now the Phones 4u Arena to win the IBF and Ring light-welterweight belts in 2005 - says the 25-year-old has reasons to be optimistic.
"Groves looked a bit fragile when he boxed Kenny Anderson a few years ago but he looks solid now," Hatton told Ringside. "He is also more confident out of the ring and in front of the cameras.
"Carl can hit and is very strong and 12 rounds is a long time to stay out of Froch's way, so sooner or later he will probably catch Groves, who has jumped up a few leagues and is a massive underdog.
"But George seems to be relishing the occasion and has the style to beat Froch, so maybe he can do it and maybe we will see a changing of the guard."
On his memorable triumph over Tzsyu, after which the Thunder from Down Under retired, Hatton added: "I was at my peak; I was young, fresh and had no miles on the clock."
"I was able to go through a very hard hitter and to see such a great champion quit on his stool was one of the greatest nights of my life.
"[The Phones 4u Arena] is great when it's sold out and packed to the rafters there is no better atmosphere, for me.
"I had so many great nights in there and could have moved my bed in there at one stage!
"Plus, there are very knowledgeable sports fans in Manchester who appreciate quality match-ups, regardless of where the fighters come from."
