Gordon Strachan believes Neymar, rather than Scott Brown, should be scrutinised for his part in the incident which led to the Celtic captain being sent off against Barcelona.
The Scotland manager has selected Brown, whom he signed for Celtic in 2007, for the home World Cup qualifier with Croatia in which the midfielder is expected to captain his country again.
Brown was dismissed with half an hour left of the Champions League defeat by Barça, after offering a sly kick at Neymar.
"You've got to remember that in South America, that's accepted," Strachan said. "In Britain your mates say, 'what are you doing? You embarrassed yourself there'.
"I find that very strange. It's not going to change now. With all that respect and handshakes thing – they go through that, then they roll about on the ground.
"It's the culture. If you've been in South America, where these people come from, you'll do anything not to go back there and you'll do anything to make a living. It's very hard to understand unless you've gone over there and seen where these people come from.
"They've had to do anything to get to where they are. We don't like it but if you understand it you can maybe see where it's come from."
Brown broke his silence on Wednesday to express his regret. "There wasn't a huge amount of contact at all, to be honest, but I have to accept responsibility for my actions, and I do," he said.
Strachan compared the incident to David Beckham's red card against Argentina at the 1998 World Cup. "We have seen it and we all go, 'wooah, maybe he gave the referee an opportunity'. But then we are going, 'what was Neymar doing?' It is like the David Beckham and [Diego] Simeone thing.
"You look at David, and then you look at Simeone and say, 'I thought he was supposed to be a hard man?'"
Strachan has included Jordan Rhodes in his 24-man party for Croatia's visit to Hampden Park on 15 October. The forward has continued his prolific scoring form at Blackburn Rovers although Strachan has said Scotland's system does not suit his style of play.
"I played with Billy Pirie at Dundee and he scored 40 goals a season but he didn't get us promoted," Strachan said. "It's all about the team. It's about what works well together."
Strachan insisted Darren Fletcher will return to playing top-level football. Scotland's permanent captain has not played for his club, Manchester United, since last December as he battles a bowel problem but has stepped up his training schedule in recent days.
"I spoke to Darren a couple of weeks ago and he's feeling good about himself," said Strachan. "You'd have to leave the medical side of things to Manchester United but he'll be back, there is no doubt about that."
