The West Bromwich Albion striker expressed his disappointment that the Boys in Green could not hold on to defeat Austria at the Aviva Stadium in World Cup qualification
The Boys in Green went behind after 11 minutes when Martin Harnik scored for Austria, but two goals from Jonathan Walters overturned the deficit. However, Bayern Munich left-back Alaba struck in stoppage time to ensure a point for Macel Koller's side.
Speaking after the game, Long expressed his dismay at the final result, which sees Ireland remain level with Austria and Sweden on eight points after five games played.
"It's devastating really," admitted the West Bromich Albion striker to RTÉ. "Four points would've been ideal [from the games against Sweden and Austria]. We deserved the three points."
Nevertheless, Long believes the side can rally around and get a result in the June qualifier against the Faroe Islands.
"We need to pick ourselves up for the Faroe Islands," he said. "We need to get the three points there. Then we have Austria and Sweden again, so it could be a big week for us.
"We need to be beating Austria, and then we have something to hold on to with the 2 hard games - Sweden at home and Austria away.
However, he finished on a negative note, suggesting that the tie with Austria in Dublin will prove to be a missed opportunity.
"It's hard to take at the moment," he added. "I'm sure we'll look back at it as two points lost, but we can't look down at the moment."
