Scotland manager Gordon Strachan says no player has given him cause to draw up rules for his squad in terms of their off-field behaviour.
A photograph of an apparently drunk Scott Brown appeared on the front page of a national newspaper ahead of Sunday's Scottish League Cup final.
Strachan was asked if he had concerns about the Celtic midfielder.
"The players have been immaculate in their behaviour on and off the pitch," he said.
"Within my jurisdiction, when I'm responsible for them and my coaching staff, they have been absolutely fantastic.
"I have not made a rule yet. The only one is the alcohol one, which is for everyone, not just the players, and that's not been broken in two and a half years."
George Burley's Scotland reign was marred by the notorious "Boozegate" incident that led to Barry Ferguson and Allan McGregor being suspended from international duty for their role in a hotel drinking session.
Celtic manager Ronny Deila has been quoted as saying that Brown had to be mindful of his public profile while praising the way he subsequently led the side to victory over Dundee United at Hampden.
That was echoed by Strachan, who said: "I think everybody's in the public realm 24 hours now and that's the way it is in football.
"But there's a line that should be drawn for everybody and not just footballers.
"These players don't get paid for coming here. They leave their families, wives, kids to come here to play a game of football.
"On many occasions, they get abused from all sections and they do it for nothing.
"I am Scotland manager and I don't think we've made rules. Nobody's broken anything, nobody's affected anything in the two and a half years, so I don't need to make rules."
Strachan confirmed he will wait until after the matches against Northern Ireland and Gibraltar before deciding Stuart McCall's future with Scotland.
McCall has taken a sabbatical from his Scotland coaching duties after taking over as Rangers manager until the end of the season last week.
The Scotland manager has no plans to replace McCall in the near future.
"We'll get through these games and then we'll re-assess it before the game in June," said Strachan, who brought McCall onto the coaching team shortly after taking the national team job in January 2013.
The match on 13 June away to Republic of Ireland could be crucial for Scotland's Euro 2016 qualifying hopes.
Before then, the Scots host Northern Ireland in a 25 March friendly followed by a visit from Group D minnows Gibralter.
Strachan is relaxed about himself and assistant Mark McGhee being a man down for those fixtures.
"We will miss his company, we will miss his input, we will miss his work, but we feel at this moment in time Mark and myself and the rest of the coaching staff can come together and pick up where Stuart's left off," he said.
"It might cut down on some Scrabble time for Mr McGhee and myself. We might have to put in some extra work.
"This is like a football side - when you go down to 10 men, the rest of the team get together, so we will do that."
