The pair clash in a re-run of their November 2013 bout, when Froch emerged victorious after a controversial stoppage in the ninth round.
However, Groves has stated that the Nottingham fighter won't get the better of him for second time when they collide in front of 80,000 fans at Wembley.
He told reporters: "You'll see a complete a performance as possible on Saturday night. I'm going to arrive - not just here in Britain but across the world. I want to be great ambassador for British boxing and that starts on Saturday night.
"I know I can do that. In the first fight the referee shouldn't have stopped the fight. I plan to perform on Saturday night and it will last 12 rounds if needs be. Round-on-round it will get better and better. I can go 12 rounds, I can go more.
"It's going to be one-sided from the start. Like last time."
Meanwhile, Froch has called the fight "the biggest" of his career.
