IBF, IBO, WBA heavyweight champion Anthony Joshua is full behind Mexican superstar Saul "Canelo" Alvarez (49-1-1, 34 KOs) to unseat middleweight king Gennady Golovkin (37-0, 33 KOs).

Canelo will challenge Golovkin, who holds the WBC, IBO, WBA, IBF middleweight belts, on September 16th at the T-Mobile Arena in Las Vegas. HBO Pay-Per-View will carry the bout.

The bout is the most anticipated boxing fight of the year, with nearly two years of hype for the match to take place.

While Golovkin is a slight favorite to win, the fight is now a lot closer in the eyes of many than it was a year ago. A year ago, the majority of pundits were siding with Golovkin to win, but now there are many who are siding with Canelo to pull it off.

Joshua is among the Canelo supporters and wants him to pull though with a victory over GGG, who last September traveled over to the UK and stopped Joshua's stablemate Kell Brook in five rounds. But before he pulled off that stoppage victory, Golovkin had taken his fair share of punches from Brook, who was moving up by 13-pounds from the welterweight division.

"I hope Canelo wins, not that I don't like Triple G. I have just been riding with Canelo for a long time," Joshua told Sports Mail.

"He's 27 and the man has achieved so much and he'll be one of the fathers. He's still a baby but he'll be one of the fathers in the sport, give him another 10 years. He'll be around for a long time and I think he'll do great things for the sport.

"So I have been riding with Canelo for a long time but it's going to be a tough fight because Triple G is from Kazakhstan, he has the good foundations of a boxer. But so has Canelo, so I'll put my money on him."
