Carl Froch and George Groves are both convinced they will emerge victorious from their eagerly anticipated re-match at Wembley on Saturday.
The pair were in confident mood at the final pre-fight press conference on Thursday, with Groves predicting exactly how he will knock out Froch in front of almost 80,000 fans at Wembley.
For WBA and IBF super-middleweight champion Froch, it is confirmation that even with a poor performance, he can get over the line on the biggest stage.
At 26, Groves is 10 years Froch's junior. The Londoner is lighter on his feet than his opponent, sharper in his angles and swifter with his hands.
But Froch is durable, cunning and with 32 professional victories out of 34 contests, his experience will prove invaluable when the adrenaline is pumping.
"You're using the 36-year-old as a question mark around whether or not I can still do it at this level," Froch said.
"But of course I've still got it what it takes and of course I can still do what I did in my twenties.
"I am performing, the output is there, I'm still doing it. It may be a cliche but age really is just a number."
