Former super middleweight champion Carl Froch is still not impressed with the resume of Gennady Golovkin, who this Saturday night takes part in the biggest fight of his pro career.

Golovkin will defend his WBC, IBO, IBF, WBA middleweight belts against Canelo at the T-Mobile Arena in Las Vegas.

While Golovkin was a strong favorite in the two years of hype, there is now a growing trend of experts who leaning in the direction of Canelo to win the fight.

Froch says the reason Golovkin is not getting enough credit, at least coming in to this fight, is his lack of competition.

The Nottingham fighter is backing Canelo to walk away with the middleweight belts.

"No one has really given Golovkin the credit or the respect he deserves, because he has not got the names on his record. Let's be honest, who has he fought? Nobody really jumps out, apart from Daniel Jacobs. Yes, he's dispatched them all, but he's not going to get that recognition until he beats a name. If he beats Canelo, it will look great on his CV, but has this fight come too late for him? He's just past his best, I think, after seeing his last couple of fights," Froch told Sky Sports.

"I reckon GGG vs Canelo is going to be a great, close fight, and I have a feeling that 'Canelo' is going to win on points, because Golovkin gets hit too much. I think both of them can get hurt, but 'Canelo' will nick it on points. If it goes like that, then potentially we could see a rematch."

A few years ago, Froch was in position for a fight with Golovkin, but decided to retire. Froch says there were no concerns over facing Golovkin - he was just unhappy with some of the terms, like the proposed catch-weight.

"When I retired, I retired at the right time, but I had no concerns about facing Golovkin. It was just all about the timing. The timing was all wrong and they wanted me to take some weight off as well. I had been out of the ring for over a year when they really started talking seriously," Froch said.

"Golovkin is far too small. I said it ages ago and I say it now, I'm too big and too strong for him. I'm not going to change my mind. I've got height, reach, strength and a granite chin. How does he beat me?"
