Antony, a Manchester United winger, responded to an assault claim brought by his ex-girlfriend Ingrid Lana by sharing a series of WhatsApp conversations from their chat.
Lana, a 33-year-old banker, claimed Antony was hostile toward her in October in an interview with Record TV in Brazil.
She accused the 23-year-old winger of slamming her against a wall after attempting to kiss her.
Police in Sao Paulo and Manchester are looking into Antony after his ex-girlfriend Gabriela Cavallin accused him of beating her four times. Antony has categorically denied any wrongdoing.
Last Thursday, two more women in Brazil came forward to accuse the £85 million player.
Rayssa de Freitas, a law student, claims she needed hospital treatment after being attacked in Antony’s Land Rover by Antony and Mallu Ohana, the ex-wife of Brazil footballer Dudu after the three left a Sao Paulo nightclub in May of last year.
Lana then made her accusations against Antony in a TV interview. “He tried to have sex with me and I didn’t want to. He pushed me against the wall and I hit my head.”
United confirmed that Antony will be absent from the club until further notice. He has not been suspended but has been granted a leave of absence with full pay to allow him to defend himself against the allegations on Sunday.
Antony posted four screenshots of WhatsApp conversations, presumably with Lana, to his Instagram account on Sunday night.
He also wrote: “I don’t want to but I’m being forced to publish a small part of the WhatsApp conversations with Ingrid, which demonstrates that we only had a single meeting, intimate and consensual.
“This matter with this fraudster will be resolved in court!!”
The person messaging Antony says, ‘If you like, I’ll wait in bed naked,’ in one of the texts.
In another, Antony complains that someone has screenshotted their conversations, adding, ‘I find it cool, so please delete it.’
In a statement to Brazilian news outlet Globo, Antony said: “I was chatting with Ingrid via WhatsApp. When she went to Portugal to go to her cousin’s birthday, she asked to come here to Manchester to meet me, with the clear intention of meeting me intimately, including asking me if I preferred red or white lingerie.
“I bought a ticket and booked a hotel for her. In fact, I met her at the aforementioned hotel and we had an intimate and consensual encounter.
“Although she insisted that we meet again for another intimate encounter, due to scheduling issues I was unable to see her again, as she returned to Brazil. Since then, I have never met her again.
“All of this that I narrate now is undoubtedly proven in WhatsApp messages, which I just do not publish in full to preserve the right to privacy.
“However, I will make available the appropriate channels, if necessary, to prove my innocence, as well as to propose the competent reparatory action and request for investigation.”
