Gambia midfielder Tijan Jaiteh was sent off in the 43rd minute for his second yellow card and the Austrians took the lead in first half stoppage time as skipper Sebastian Proedl headed home Veli Kavlak's free-kick. Gambia were desperately unlucky not to equalise when Abdoulie Mansally's curling free-kick was tipped over the top by Michael Zaglmair after an hour and the Gambia midfielder hit the post with another set-piece attempt a minute later.
Zaglmair then made a great save with his legs to deny Ousman Jallow as Gambia began to press hard and they drew level after 69 minutes. Austria midfielder Martin Harnik was caught in possession inside his own area before Pierre Gomez finished classily with the outside of his left boot, leaving Zaglmair rooted to the spot. Hoffer got the winner nine minutes from time when he blasted the ball past the helpless Joseph Gomez.
