Triple GGG has knocked out 33 of his 37 opponents and is known as the most powerful puncher in middleweight boxing and already holds the WBC, WBA and IBF titles.
But Canelo is one of the best counter-punchers in world boxing and many rate him as one of the very best pound-for-pound fighters on the planet.
The 27-year-old has just one defeat, to the legendary Floyd Mayweather, in his 51-fight professional career but is a slight underdog tonight and could add a second.
- Canelo vs GGG expected to start around 4.15am UK time
- Nicola Adams fight OFF as opponent fails pre-fight blood test
- Tyson Fury talks up comeback against Anthony Joshua
Canelo vs GGG LIVE – Latest build-up to Gennady Golovkin vs Saul Alvarez
12.40am: Saunders and Monroe Jr are heading into a last round but it looks like the champ will hang onto his WBO middleweight belt.
12.15am: Nicola Adams may not have been in action tonight but her girlfriend Marlen Esparza has been fighting.
The 28-year-old has secured her third professional win, from three fights, taking a unanimous decision after a polished display against Aracely Palacios.
Back in London meanwhile, Billy Joe Saunders and Willie Monroe Jr are at the halfway stage of their WBO middleweight title fight. Saunders looks to be ahead on points but is not dominating yet. Tight fight so far.
11.40pm: Let’s have another predicition shall we? This time it’s Amir Khan, who was knocked out by Canelo last time out.
“I can tell you Canelo is a class act,” Khan said.
“He is a good boxer, he moves very well and he hits very hard.
“People say that Golovkin is the power puncher in this fight but I think they may be wrong.
“I think Canelo is one of the biggest punchers in that division.
“What I found out about Canelo is that he hits and moves, his footwork is very good and he has brilliant upper body movement which Golovkin is lacking.”
11.10pm: Bad news for Nicola Adams as her fight on the undercard of Canelo vs GGG has been called off at the last minute after Alexandra Vlajk had an issue with a blood test.
Adams had been due to get in the ring at 3pm in Las Vegas – or 11pm in the UK – a few hours before the middleweight title clash between Alvarez and Golovkin at the T-Mobile Arena but was told less than an hour before that her fight had been cancelled.
Gutted for her.
10.45pm: Honestly, I’m like a kid at Christmas today. Except it’s a Christmas where we get presents the day before as well. Because there is LOADS of boxing this evening on both sides of the Atlantic and we’ve got coverage of it across the site.
For example, you have a look at Daniel Dubois’s 48-second knockout of AJ Carter or read about how Anthony Yarde had to deal with a hospitalised grandmother just hours before he weighed in for his fight. Both of those fights came on the undercard of Billy Joe Saunders vs Willie Monroe – they should get in the ring in about an hour’s time.
Tyson Fury is also in the house in London – talking up a comeback and an “easy” fight against Anthony Joshua too!
“I’ve got to get some weight off,” Fury said.
“I’ve lost nearly two stone in two weeks so everything is going really well for me at the moment.
“I’ve turned my life around. I’ve done a U-turn on everything and I’m feeling a lot better than I did before.”
10pm: It’s here. It’s finally here. Forget David Haye vs Tony Bellew, forget Floyd Mayweather vs Conor McGregor. This is the real boxing contest of the year. Probably the decade. Maybe the century.
I don’t think this is the last time we will see this fight and to be honest, I’d be happy with that.
We’ve got a few hours to wait before the fight gets underway in earnest – so we’ll keep you entertained. I spoke to Tony Bellew about the fight earlier this week and here’s what he told me.
“It’s an amazing fight and an unbelievable spectacle. If Canelo can take Triple G’s power, he wins,” Bellew told Express Sport.
“That’s all it’s about for me. I just don’t see how Triple G can outbox him.
“Canelo is probably the best counter-puncher in the whole game right now. He is defensively very good and his counter-punching skills are off the charts. He’s got power in both hands.
“The thing with Gennady Golovkin is whether he make Canelo fold under the pressure, whether he can make power the deciding factor.”
