Amanda Serrano claims she did not lose her Madison Square Garden bout with Katie Taylor last weekend.
The Puerto Rican, who was originally humble in defeat, has now claimed that Taylor should not have had her arm raised in victory.
The Bray Bomber won the fight via split decison after two judges scored it 97-93 and 96-93 in her favour, with a third giving it 96-94 to Serrano.
But Serrano took to social media on Saturday night to state that she now believes she did not lose the fight.
The 33-year-old tweeted: "One week later…Had a chance to reflect on the fight against Katie. It was very close, but I did not lose. That I am certain of. Next time I will leave no doubt. Can’t Wait!
"I walked in a champ and I walked out a champ."
Serrano later called for the rematch to take place on the same card as a second bout between Canelo and Bivol, after the Russian recorded a shock win over the Mexican on Saturday night in Las Vegas.
Taylor was in attendance at the T Mobile Arena and reiterated her desire to face Serrano at Croke Park later this year.
The undisputed and undefeated lightweight champion told DAZN: “A rematch would be brilliant. I’m up for any challenge, I want to fight the best out there.
“I would absolutely love to fight in Ireland. A big fight in Croke Park with 80,000 people. That would probably be the only thing that could top what happened last week.
“Imagine filling 80,000 seats that would be very, very special. It would be easy to sell as well I think.”
On the MSG fight, Taylor added: “It is going to be in for Fight of the Year as well. It was just an amazing night for the sport.”
Just one week on from the history-making fight in New York, the majority of Taylor's facial injuries suffered in the bout appeared to have cleared up.
The undisputed lightweight champion bled heavily from a cut above her eye during the ten-round contest.
Taylor was also badly bruised after the bout, with Hearn having to wipe blood from the left side of her face at one stage during the post-fight press conference.
