Eddy Reynoso, the head trainer for WBC, WBA, IBF middleweight champion Saul "Canelo" Alvarez, wants to see his boxer in a unification bout in 2019.

On Saturday night at the T-Mobile Arena in Las Vegas, Canelo earned a unanimous decision over Daniel Jacobs with three world titles on the line.

Canelo won on all three judges’ scorecards, with two having it 115-113 and the other 116-112.

Reynoso was very impressed with his boxer's work during the fight and had him make adjustment as the contest played out.

"I loved the way he flexed his waist, his work off the ropes when Jacobs had him against the ropes, but I really like how he moved his waist," Reynoso said.

"We saw that he was working the head too much, but because of Jacobs mobility he was always taking a step back, getting off-balance and creating problems, so we kept telling him to go for the shoulders, work more on the shoulders, because then he'd get him."

This was Canelo’s first fight of 2019, but the second fight of his five-year 11-fight $365 million deal with the boxing streaming service DAZN.

Since losing to Floyd Mayweather in 2013 Alvarez has gone 10-0 with one draw including five knockouts.

At the age of 28, he is still in his prime, having improved his record to 56-1-2 with 35 knockouts.

Technically, Canelo is still the WBA "regular" champion at super middleweight - a title he won in December with a three round blowout of Rocky Fielding in New York City.

They would like to face WBO 160-pound champion Demetrius Andrade, should he defeat Maceij Sulecki next month.

If they are unable to make a deal to face the WBO champion, then Reynoso would like to see Canelo unify titles at 168 - where a big money bout with Callum Smith could be waiting.

"We'd love to unify at 160, at that weight, if the champ is available - but if that's not available then we'd like to unify at 168," Reynoso said.
