Noel King's side came from behind to open their Uefa Under-21 European Championship qualifying campaign with three points in Toftir
Watford's Sean Murray had the first chance of the game from a free-kick, but it was the hosts who took the lead thanks to Gilli Sorensen's 14th minute strike. The Faroes were ahead for less than 10 minutes as the Boys in Green equalised through Samir Carruthers.
After going in level at the break, Ireland looked brighter in the second-half, with Carruthers continuing to impress. The MK Dons loan signing turned provider for Ireland's second goal, sending in a corner which was claimed by Matt Doherty as it ended up in the net.
Aaron McCarey did well to keep Sorensen from levelling the tie again, before Ireland put the result beyond doubt with two late goals. Aiden O'Brien netted two minutes from time before Matt Doherty scored in stoppage time. With victory guaranteed, Aston Villa winger Jack Grealish was introduced with a minute remaining to win his first cap for the under-21s.
After the game, King spoke of his pleasure at the performance. "It was very much a battle, it was dogged performance," King said. "We stuck with it and showed great desire. It was a tough start but they kept going right to the end.
"Their goal was a giveaway but the whole team made up for it. The reaction was very good. Samir scored a great individual goal but everybody contributed. Matt Doherty did very well breaking from midfield and it was pleasing to see him score two important goals."
The Boys in Green face Germany at the Showgrounds in Sligo in their next qualifying game on September 9.
