Billy Joe Saunders snuck in an insult directed at Canelo Alvarez and trainer Eddy Reynoso toward the end of an Instagram Live video Monday with Eddie Hearn.

Saunders asked his promoter to identify his “favorite all-time trainer at the moment” during their casual conversation.

“My favorite all-time trainer at the moment?,” Hearn replied. “What I’ll do is I’ll go outside of Britain. I think Eddy Reynoso’s a good trainer, Canelo’s trainer.”

Saunders sarcastically took the opportunity to mention Alvarez’s performance-enhancing drug suspension in 2018.

“I think, yeah, but [Reynoso] can’t really speak a lot of English, so we can’t really know,” Saunders said, referring to Reynoso’s training skills. “We don’t know what he’s saying. Do you know what I mean? Also, they do good meat out there as well, you know, good beef.”

By mentioning meat, England’s Saunders alluded to Alvarez testing positive for clenbuterol two years ago. Alvarez blamed contaminated meat in his home country of Mexico for having that banned substance in his system when he was tested by the Voluntary Anti-Doping Association.

The Nevada State Athletic Commission still suspended Alvarez for six months, which caused a four-month postponement of his middleweight championship rematch against Gennadiy Golovkin. Alvarez beat Golovkin by majority decision in their second 12-round encounter in September 2018 at T-Mobile Arena in Las Vegas.

The 29-year-old Alvarez (53-1-2, 36 KOs) is expected to challenge Saunders for the British southpaw’s WBO super middleweight title in his next fight. They were supposed to meet May 2 at T-Mobile Arena, but their 12-round, 168-pound championship match has been postponed indefinitely due to the coronavirus pandemic.

Reynoso, meanwhile, has been widely commended for assisting Alvarez in becoming one of the top boxers, pound-for-pound, in the sport. He also has been praised for helping 20-year-old lightweight Ryan Garcia improve over the past year.

The Boxing Writers Association of America recently named Reynoso its “Trainer of the Year” for 2019.

“We’ll see how good he is,” Saunders said, “when I box Canelo.”

Saunders experienced his own PED ordeal later in 2018.

The 2008 Olympian was supposed to make a mandatory defense of the WBO middleweight title against Demetrius Andrade in October 2018 at TD Garden in Boston. Once Saunders tested positive for oxilofrine, a substance banned by VADA, the Massachusetts State Athletic Commission denied his request for a boxing license and he was subsequently stripped of his belt by the WBO.

Andrade (29-0, 18 KOs), of Providence, Rhode Island, instead beat Namibia’s Walter Kautondokwa (then 17-0, 16 KOs) by unanimous decision in a 12-round fight for the then-vacant WBO 160-pound championship. Andrade knocked down Kautondokwa four times on his way to an easy victory.
