Northern Ireland now face a daunting away match against reigning World champions Germany.
The side notched-up a 4-0 home win against San Marino at the New National Sports Stadium on Saturday night.
But manager Michael O'Neill said his boys were under no illusion just how tough a challenge they face in Hanover on Tuesday night.
O'Neill, speaking in a post-match press conference after the San Marino win, said Germany were still smarting after failing to win the Euros and had already shown they are out to prove a point as they set out on a campaign to retain their World Cup trophy.
Northern Ireland last played Germany in the Euros in June when the World Champions narrowly beat them 1-0.
