The match will be Scotland's last before the team embark on the European Championship qualifying campaign in September.
Unbeaten in five matches, optimism is growing amongst the Tartan Army and Strachan says his players are showing no signs of letting up.
"We worked yesterday in the pouring rain and I enjoyed myself - people say it's a lot to do with the coach's enthusiasm but it works both ways," Strachan said.
"The enthusiasm you get from the players keeps your battery going as a coach and I like working with them."
"The lads are full of enthusiasm, which is great, and it's easy to coach when the players are like that. The enthusiasm rubs off on me, it's great and I enjoy it."
Over the past year Scotland have beaten Croatia twice and also recorded victories over Poland, Norway and Macedonia.
And Strachan says he is trying to improve his team's attacking fluency but insists there has been no magic formula to Scotland's upturn in results.
"It's not that complicated, football," Strachan said. "You get the ball, you try to score. You haven't got the ball, you don't let them score - it's not that complicated.
"People try to convince you it's super-complicated and they can make miracles happen - it's all about players.
"We just have to keep trying to do the things we've been doing. We want to try to be more positive, to get more people in the box.
"That's what we've been working on over the last couple of days, we want to make sure the main striker isn't isolated.
"We've also done our usual training but we're trying our best to get as many players forward and around the box as possible."
