Ukraine dumped a poor Scotland out of World Cup qualifying with a 3-1 win at Hampden Park on Wednesday night.
Andriy Yarmolenko and Roman Yaremchuk struck either side of half-time, before Callum McGregor gave Scotland hope late on. But Artem Dovbyk sealed a Qatar 2022 showdown in Cardiff on Sunday with the last kick of the ball.
Scotland boss Steve Clarke told Sky Sports: "It's a disappointing night. You have to be honest, the best team on the night won.
"I wish Ukraine luck in Cardiff, but you have to wish the Welsh luck as well. First half we didn't play enough, we didn't get the ball down.
"I made the change at half-time and we didn't give ourselves the chance to utilise that.
"John (McGinn) missed a big chance that would've given us half an hour to get back into the game. We chased it well, we tried as hard as we could.
"Now is a night to suffer, we'll suffer together. It's going to take at least 48 hours just to move on. When you lose a game of this magnitude it hurts. We will try build into the Nations League campaign."
