It leaves Michael O’Neill’s men sitting fifth in Group H after winning two of their eight qualifying fixtures to date – both of which came against San Marino, including Saturday’s 3-0 triumph in Belfast.
The Green and White Army turned out in their numbers once again to get behind Northern Ireland. Here are the best fan photos from the stadium.
