Steve Clarke told his Scotland squad to justify his confidence in them by getting to another major tournament following failure to reach the 2022 World Cup in Qatar.
Clarke admitted he and his players were suffering after their 3-1 defeat by Ukraine in their play-off semi-final at Hampden Park.
Ukraine skipper Andriy Yarmolenko deservedly put the visitors ahead in the 33rd minute and Roman Yaremchuk doubled that lead three minutes after the break.
