Scotland captain Andy Robertson revealed he was next in line for a penalty but was struggling with a hamstring complaint as his country edged past Serbia for a spot in Euro 2020 on Thursday.
Steve Clarke's side had taken the lead in the 52nd minute through Ryan Christie but Real Madrid striker Luka Jovic equalised for Serbia in injury time.
The two sides could then not be split in extra-time as the qualifier was forced to a shootout with Scotland converting all five of their efforts before Aleksandar Mitrovic was denied by David Marshall.
