MELBOURNE midfielder Brent Moloney has stepped down from the club's leadership group, and relinquished the vice-captaincy, after admitting to being drunk during the early hours of Monday morning.

Moloney has also admitted he has a problem with binge drinking.

But the 27-year-old has vehemently denied that he urinated on the bar inside a St Kilda nightspot, as was alleged by a caller to a Melbourne radio station.

"I'm disappointed and embarrassed on what happened last night," Moloney told a press conference at AAMI Park on Monday afternoon.

"Obviously I'm not setting the right standards for this footy club, and I'm very disappointed on losing the vice-captaincy.

"But I'm going to keep leading the way I have the past two or three years."

In an effort to overcome his problem drinking, Moloney plans to seek help from the AFL Players' Association.

"I don't drink a lot, but when I do I seem to consume too much," he said.

The Demons will not be imposing a suspension on Moloney, meaning he can be chosen in the team to play the Gold Coast Suns at the Gabba on Sunday.

"Whether we select him or not's another thing," Melbourne coach Dean Bailey said. "But he'll certainly be available."

Moloney has been in outstanding form so far this season and was one of the key players in the Demons' victory over the Brisbane Lions on Sunday afternoon, but his late-night indiscretion overshadowed his impressive on-field efforts.

"It's a difficult situation for Brent because he has given up a lot, what he loves, and he's worked really hard in the last couple of years," Bailey added.

"I think it takes a great deal of courage to stand in front of people and suggest that he has an alcohol [problem]. He'll certainly seek to remedy that concern that he has.

"He's player who's worked his arse off in the last two or three years to get to where he has, and what's been taken away from him is a significant thing.

"I know he'll work incredibly hard to regain the trust of his teammates and also to resurrect his position within the Melbourne Football Club.

"I'm sure that he'll get his best foot forward and, giving up what he has, it might be the making of a better player."

Speaking about the allegation that Moloney had urinated on the bar, Melbourne chief executive Cameron Schwab said: "We've spoken to the proprietors of the bar in question.

"They've confirmed they've gone through all of the tapes, spoken to all of the people who were involved and working on the night, and they confirmed that the incident purported to have happened didn't occur."
