Scotland escaped a tougher-than-anticipated trip to the Faroe Islands with a nervy 1-0 victory thanks to Lyndon Dykes' late winner.
Steve Clarke's side had appeared set for a frustrating night against a side they had swept aside by a four-goal margin in the reverse fixture.
The hosts first squandered a string of first-half chances as Scotland struggled and the Faroe Islanders seemed likely to cling on for a point.

Yet up Dykes popped in the dying embers of the contest to continue his fine international goalscoring form and keep Scotland on track for a play-off place in World Cup qualifying Group F.
Also in good goalscoring touch was Finland's Teemu Pukki, who went past the legendary Jari Litmanen as his nation's all-time leading scorer during their win over Kazakhstan.
Pukki powered the Finns to a 2-0 away win at the Astana Arena in Nur-Sultan to overhaul arguably his country's finest ever player.

In beating the Austrians, Denmark followed their southerly neighbours Germany in securing qualification for next year's World Cup in Qatar.
Finally, Andorra completed the double over their fellow landlocked stragglers San Marino to secure the penultimate place in Group I.
Midfielder Marc Pujol scored his fourth goal in a more than 20-year international career to help his side to victory.
