Rooney's agent has strenuously denied any wrongdoing

The alleged incident happened in Manchester nightclub Ampersand in the early hours of Sunday after Everton's 4-3 defeat by Manchester United.

Greater Manchester Police refused to confirm the names of those involved.

Wayne Rooney's agent, Paul Stretford of Proactive Sports Group, said any allegations were "entirely false" and said Rooney had himself been spat at.

A spokesman for Greater Manchester Police said: "Greater Manchester Police have received a complaint of an alleged common assault from a 23-year-old woman from Skelmersdale.

"It is claimed that an 18-year-old man spat in the woman's face in a Manchester nightclub at around 3am on Sunday 8 February."

The spokesman said the complaint would be fully investigated.

Mr Stretford, of Proactive Sports Group, said: "Any allegations being made against Wayne are fatuous and entirely false.

"The only untoward incident Wayne was aware of in the nightclub in question was when he was subject to a volley of verbal abuse from a young woman. Although he did not respond in any way, she spat at him and was subsequently ejected from the nightclub.

"Wayne was enjoying a perfectly legitimate night out after a big match. He was entirely sober throughout the evening.

"Wayne will cooperate fully with any police investigation. It is not something that causes Wayne or his management a moment's concern."
