The Scots' hopes of reaching the 2014 World Cup finals in Brazil are all but over after taking just two points from their first four qualifiers to leave them bottom of Group A.
The Blackburn striker is looking forward to a new era under Strachan which starts with a friendly against Estonia at Pittodrie on Wednesday night where he hopes the Scots start to enjoy a rub of the green.
"I think we need a bit of luck to be honest," said the 22-year-old.
"When I was watching the games, particularly before I was even involved in the set-up, I was thinking a roll of the ball here or there or a decision by the referee...
"I think you can look back and see how many points are decided by the luck of the draw sometimes.
"Hopefully over the course of a certain amount of games or a couple of years, your luck changes and you do manage to get a goal or two more.
"But all you can do is keep working hard and ploughing on and hopefully your luck does change."
