Ex-Hearts midfielder Ian Black was surprised and disappointed to be jeered on his Scotland debut in the 3-1 victory over Australia at Hibernian's Easter Road.
The Rangers player, whose last game for Hearts was the 5-1 Scottish Cup final win over Edinburgh rivals Hibernian, was booed by a section of the crowd as he joined the fray during Wednesday's friendly and his every touch was met by a mixture of cheers and jeers.
Black's inclusion in the squad proved controversial given his move to the Third Division to link up with Rangers.
He said: "It's disappointing that it's your so-called home fans but you put it down to maybe where we are playing.
"It is a surprise but I've had that a lot throughout my career so I'm used to it and just get on with it.
"It doesn't faze me, I think if you let that faze you it's going to affect you in the long run so you have got to be big enough to get on with it.
"I'm big enough to get on with it and I've proved a few people wrong there by getting the opportunity."
Black's Ibrox team-mate Lee Wallace was omitted after manager Craig Levein said it would be difficult to pick Rangers players in the circumstances following their recent demotion, although Black's selection came amid injuries to a number of midfielders.
The 27-year-old's inclusion was also unpopular with some supporters given his combative approach to the game, but he was unclear why he was targeted.
"It could have been a bit of everything, but I'm big enough to get on with that and nothing was going to get in the way of me coming on tonight and enjoying every minute of it," he said.
