Gordon Strachan hailed goalkeeper Alan McGregor after his impressive display helped Scotland win 1-0 in Prague.
The Hull City keeper made a series of important saves to keep the Czechs out and earn the Scots a morale-boosting win.
“I thought he was fantastic in the first half, when he had to make some really great saves,” said Strachan.
“In the second half he had to be really professional and take crosses and tidy up back passes and things like that.
“I wish he didn’t have so much to do in the first half but we sorted it out. We didn’t sort it out tactically, we played the same way. We just closed down better and tackled better. If anyone is thinking it was a tactical move in the second half no, it was just the players.”
Strachan was also pleased his selection “gamble” paid off as a number of fringe players shone. “There were a lot of players you would expect to start the game who weren’t here tonight, so that’s a huge bonus,” he said. “It is a bit of a gamble when you come to a place like this without a full squad.
“But the group has made it a good night. A lot of guys in the group have done themselves proud, especially in the second half.
“They can all be proud of what they have done, even the guys who didn’t get on. They have worked hard too. We did a double session the other day. We have to do that because we are not a great side. But we can turn into a decent side by working hard.”
