Brazil have dropped Manchester United winger Antony following allegations of abuse by his former girlfriend.

The Brazilian football federation said the 23-year-old had been withdrawn from the squad after "facts became public" that "need to be investigated".

Brazilian news outlet UOL published allegations made by Antony's ex-partner on Monday.

Police in Sao Paulo and Greater Manchester are investigating the claims, which the player has denied.

"I can calmly state that the accusations are false and that the evidence already produced and the other evidence that will be produced demonstrate that I am innocent of the accusations made," Antony said on social media.

 Antony is accused of attacking his former girlfriend Gabriela Cavallin "with a headbutt" in a Manchester hotel room on 15 January, leaving her with a cut head that needed treatment from a doctor.

She also alleges she was punched in the chest, causing damage to a silicone breast implant, which required corrective surgery.

Antony added in his statement on Monday that his relationship with his former partner was "tumultuous" but insisted he "never committed any physical aggression".

In June, he also said that his former girlfriend had falsely accused him of domestic violence.

Greater Manchester Police (GMP) said it is "aware of the allegations made, and enquiries remain ongoing to establish the circumstances surrounding this report".

 Antony has been replaced in the Brazil squad by Arsenal striker Gabriel Jesus for the upcoming World Cup qualifiers against Bolivia and Peru.
