Carl Froch has predicted that George Groves might consider retirement after he inflicts a crushing defeat on Saturday night.
The 25-year-old Groves is considered one of the rising stars of British boxing and he will challenge Froch for his WBA and IBF titles, live on Sky Sports Box Office.
But Froch is not impressed by the challenger's undefeated record or his brash behaviour ahead of their super-middleweight showdown in Manchester.
The Nottingham man dished out a brutal stoppage loss to Lucian Bute last year, another undefeated fighter, and he intends to destroy Groves' confidence with a similar knockout defeat.
"I've got George Groves on Saturday, it's a big fight and these two world titles mean everything to me," he told Sky Sports News.
"I'm taking it very, very seriously and George Groves is in a world of trouble, and he's going to get an absolute shock on Saturday night. Not only am I going to beat him, I'm going to beat him in spectacular fashion and potentially end his career.
"He's not going to see that one coming, because there are a lot of fighters that I've fought that are unbeaten, before I fight them and they don't want to come back to the ring, they don't want to fight again.
"We'll see how George Groves comes back from this loss, but it's going to be a devastating defeat for him."
Froch insists he does not want to finish off Groves in swift fashion as he hopes the fans are given value for money.
Groves' pre-fight taunts have got under Froch's skin and he is keen to punish his rival for up to eight rounds before silencing him in explosive fashion.
"With boxing, I get the chance to set the record straight and make sure I put that right," he said.
"There's no better job for me and more satisfying job for me to do other than give George Groves a pasting. I'm looking forward to doing that. I just hope the referee doesn't jump in early and I also hope I don't knock Groves out too early.
"Once I start hitting him on his glass jaw, he's going to struggle to withstand the pressure and the pain he's going to endure.
"Hopefully he's super fit and he's been training very hard because it means his legs will be stronger, so when I do start to connect on his chin, and I will start to connect on his chin, hopefully he doesn't fall over straight away."
"When asked how long the bout will last, he added: "I'd like this fight to go on between six and eight rounds. The fans deserve a good night.
"Trust me the people who are going to be tuning in and buying the event are going to be getting their money's worth, because I'm in a ferocious mood and I cannot wait to absolutely serve a whooping on George Groves. I wouldn't miss out on this one because I'm really looking at doing a job on Groves."
