Trainer Jeff Mayweather, the uncle of former five division world champion Floyd Mayweather Jr., was at one point convinced that Gennady Golovkin would easily defeated Saul "Canelo" Alvarez - but that is no longer the case. He now views the contest as a 50-50 proposition.

The two boxers have long discussed the possibility of fighting each other, but the contest has never come together. They promoters are discussing the possibility of having them fight each other this coming September during Mexican Independence Day weekend.

In some of his recent fights, Golovkin has displayed some defensive flaws - which in turn has changed the opinions of a lot of experts when it comes to Canelo's ability to beat him.

Canelo is scheduled to return on May 6th in a catch-weight bout against Julio Cesar Chavez Jr. The two fighters are going to collide at 164.5-pounds.

On the other side, Golovkin will make a mandatory defense of his IBF, IBO, WBA, WBC middleweight titles against Daniel Jacobs at New York's Madison Square Garden in New York City.

Should Golovkin and Canelo win their respective fights, then it is expected - at the moment - that they will face each in the fall.

"Earlier on I was leaning towards Golovkin but as the fight grows closer, I start leaning more towards Canelo because Canelo is the more all around fighter. Canelo has defense, he throws great combinations, can move on his feet. Golovkin is a decent boxer but for the most part he just goes for the kill and he’s not going to always land a shot, and Canelo can punch too, so nobody knows what ‘GGG’ can take," Jeff told On The Ropes Boxing Radio.

"Unfortunately for Golovkin, he’s in a division where he’s the king but everyone else is so much inferior to him. It’s great to be king but if you want to be great, you have to step up to the next weight class or you have to step up to the opponents that people want to see you fight. Don’t get me wrong, the Canelo thing is business, and Canelo is basically milking his position as long as he can before he takes that kind of risk, and it makes sense. At the same time, it’s a real fight that can actually go either way."
