Scotland Under-21 manager Billy Stark believes a disciplined approach is benefiting his charges ahead of Wednesday night's friendly with Italy.
Under Stark's tutelage, Scotland have collected only three yellow cards from five matches of their European Championships qualifying campaign so far and that appears to be contributing to success.
Stark's side trail leaders Holland, a team against whom they have claimed four points from two games, with three matches remaining, with Wednesday night's friendly against Italy at Easter Road vital preparation for the remainder of the campaign.
Stark said: "We want disciplined players, not only in terms of how they react in the game, to a referee, but also their discipline in terms of their role for the team.
"Players come into a team with lots of different abilities and the good teams are able to find a way to get each individual to express those abilities. I think that's something they've done very well."
On the specific subject of addressing officials, Stark added: "I don't recall a referee ever changing his decision because a player questions it.
"If referees feel they're being shown a bit of respect then they'll return that."
Stark tonight is set to shuffle his pack, with Chelsea's former Celtic forward Islam Feruz in line for his debut aged 16 years and 197 days.
There is talent at Stark's disposal, even in the absence of prolific striker Jordan Rhodes, who is focussing on Huddersfield's promotion bid from npower League One.
It is possible some are in contention for the Olympic tournament, even though the Scottish Football Association oppose a Great Britain team.
Asked whether he was aware of any of his players being on Stuart Pearce's short list, Stark said: "I wouldn't have a clue.
"It's been debated long and hard. It's down to the individuals."
