Former two division world champion Billy Joe Saunders is not ruling out the possibility of an upset win by Caleb Plant, who faces Mexican superstar Saul "Canelo" Alvarez this weekend.

Plant will stake his IBF super middleweight title against Canelo, who holds the WBC, WBO, WBA titles at the weight, in a high stakes unification at the MGM Grand in Las Vegas. The contest will headline a Showtime Pay-Per-View card.

Saunders collided with Canelo back in May, in a unification clash in Texas.

Canelo gave Saunders his first career defeat, by way of an eight round stoppage to unify the WBO, WBA, WBC titles at 168. Saunders sustained a fractured orbital bone in the eight.

 Saunders indicates that Plant must stick to a game plan and stay focused throughout the fight.

“I don’t think he’s the invincible man. I think that Plant’s got a very good boxing brain, he just needs to maintain his distance. Make sure you’re out of distance, don’t just think you’re out of distance because that’s the difference when you’re in with world level and elite [level]. He’s gotta make sure to be on his game all the way, I think he’s gonna give Canelo a good fight,” Saunders explained to Talk Sport.

“Even with it being Canelo, sometimes you can feel very comfortable. I think that’s the time where you’ve gotta realize you’re in there with an elite fighter, not a world class fighter and Canelo is an elite fighter. But Plant’s got all the tools to cause him problems… He’s obviously gotta keep it at long distance. Keep it very busy for the first six rounds and finish strong. He’s gotta certainly maintain that jab. Being orthodox – I was southpaw and that causes more problems – so he’s open to more counters obviously than what I would’ve been. You’ve gotta maintain your range at safe distance and box nice, and hopefully the judges score the true boxing scorecards, rather than the name of Canelo.”

At the end of the day, Saunders backing Canelo to become the first boxer to unify the entire super middleweight division in the four belt era.

“I’m gonna go with Canelo on points because of the reason of being Canelo,” Saunders said.

“I know how hard it is to get a decision and what tricks they might play leading up. [Plant] can’t let any of that get to him, completely brush it over his shoulder and hopefully let his boxing do the talking.”
