World Cup 2016: NI win over San Marino essential says O'Neill

Northern Ireland manager Michael O'Neill says it is crucial they see off San Marino at Windsor Park to maintain momentum in the World Cup qualifying campaign.

NI started their Group C schedule with a draw away to the Czech Republic and will be expected to bag three points in their second game on Saturday night.

"Obviously we have a difficult match against Germany coming up but the key is to win this first match," said manager O'Neill.
