Despite Breazeale standing just metres away from him, Gray told Wilder the world wants to see Wilder fight better opponents.
Clearly, Breazeale heard every world of it.
Boxing commentators labelled Gray's suggestion "disrespectful" despite Breazeale only just getting back to his feet after Wilder's savage first round walk-off knock out.
Wilder was also caught off guard by Gray's honest question about why the American champion has been unable to organise a fight against Joshua or a re-match with English controversy king Tyson Fury.
"I know a lot of people want to know when the (Anthony) Joshua fight happening. All these fights are in discussion. No doors are closed; all parties that's involved are talking," Wilder said in response to Gray's question.
"It's going to take my team and his team, maybe me and him as well, to sit down, handle this and squash everything and get this fight done for the fans.
"This fight will happen. With patience comes time and I just want [the fans] to have patience and give it a little time to make this happen.
"We risk our lives, so we want to make sure we get the best and most money that's possible. Let us get our time to iron out our differences, and you guys will know when it happens."
Wilder's brutal display against Breazeale has only further built the hype surrounding a fight with either of the two English sluggers.
Wilder got back into the win column on Sunday, knocking out Breazeale with an overpowering right hand in the first round to defend his heavyweight title.
"There's been a lot of animosity and a lot of words that were said and it just came out of me tonight," Wilder said.
Wilder hurt Breazeale with a right to the head early in their fight at Barclays Center, but the challenger had recovered from that early onslaught. But there was no coming back from the right later in the round that immediately dropped Breazeale, who was trying to get up as referee Harvey Dock counted him out at 2:17 of the round.
"When I hit him with the right hand the first time, his body language changed," Wilder said.
And with the last one, Breazeale's body language crumpled.
Wilder (41-0-1, 40 KOs) was coming off his draw against Fury in December, the first fight of his pro career that wasn't a victory.
He wanted a rematch with Fury or a unification match with fellow champion Joshua, but settled for a mandatory defence of his WBC title when those couldn't be made.
He ended it quickly, finishing off Breazeale (20-2) after being pushed hard in each of his last two fights.
