The 56-year-old claims that Scottish footballers should stop moaning about foreign players and spend more time on the training ground.
"We need to do something ourselves; stop feeling sorry for ourselves in Scotland," he told BBC Radio Scotland. "Don't go to snooker halls or watch the telly. Practice longer. If you do that, you will become a better player.
"Work harder, just work harder to be a better player. Discipline yourself to be a better player. Do more hours with the ball to be a better player. Put more hours in - don't sit back and moan and groan about foreign players. We must get better ourselves. If you work harder at the game, we'll get better.
"If the standard comes up, the ordinary foreign player won't be here. When we were at Coventry, the Under-21s had to train at least three afternoons per week. Not train; train in the morning and work on your technique in the afternoon."
Strachan was appointed Scotland manager in January 2013.
