The two lightweights will meet at the Rumble on the Humber in a hugely-anticipated showdown.
Campbell (1/3 to win by KO, TKO or knockout) is looking to win world honours after securing European gold and a World Championship silver alongside his gold from London 2012 as an amateur.
The 27-year-old is currently 11-0 and he has stopped nine of his opponents inside the distance. Coyle, on the other hand, has enjoyed a rollercoaster career in recent years.
He lost to Gary Sykes and Derry Matthews earlier in his career but he has won six fights on the bounce as he tries to challenge for world honours in the future.
Although Campbell has admitted he cannot overlook his opponent, he is adamant he will prove his class on Saturday night.
“I believe in facts,” he told Sky Sports. “There’s levels in boxing and I believe I’m a fair few above him.
“I’ve got speed, I’ve got power, I’m switched on and I’m smart. That’s because I’m consistent and that shows in the professional ranks too – you’ve seen every fight that I get better and better.
“I take each and every opponent the same, and I prepare the same. Saturday night is about going out there and showing everybody how good I am. I want to go to the top in this game, that’s what it’s about.”
He added: “Saturday night will be a showcase of my skills then I can move upwards and onwards.”
