WBO welterweight champion Manny Pacquiao has given IBF, IBO, WBA, WBC middleweight champion Gennady Golovkin (37-0, 33 KOs) the edge to defeat Saul "Canelo" Alvarez (49-1, 34 KOs), who officially makes his move to 160-pounds.

The fight between Golovkin and Canelo takes place on September 16th at T-Mobile Arena in Las Vegas.

Pacquiao is very familiar with both Golovkin and Canelo. At one time his team was actually mulling the possibility of a catch-weight bout with Canelo.

"I watch boxing, I enjoy watching GGG, Canelo. It will be a good fight, it will be a tough fight, but GGG has the advantage with power and aggression. We do not know if it's going to be by points or a knockout, but [either of] the two are good," said Pacquiao.

Two weeks ago, Pacquiao's head trainer Freddie Roach also gave his take on the contest.

There was a time when Roach tabbed Golovkin as the heavy favorite to walk right through Canelo with a devastating knockout. But Roach's opinion has greatly changed after Golovkin, now 35-years-old, began to show some vulnerabilities in his two most recent outings. After stopping 23 opponents in a row, Golovkin was forced to go the full twelve round distance back in March when he secured a close points win over Daniel Jacobs.

Roach now views the fight as a 50-50 proposition.

"At one time everyone thought that Golovkin would kill him and so forth, but I don’t think people think that anymore. Alvarez has become a pretty good fighter and he’s really progressed in his career, he’s gotten better and better every fight. He looked great in his last fight and I think him and Golovkin are dead even at this point," Roach told On The Ropes Boxing Radio.
