Northern Ireland will look to gain the upper hand in their first leg World Cup qualifier play-off match against Switzerland at Windsor Park, Belfast tonight. From a betting perspective I suggest backing Norther Ireland to Win and the match to end with Under 2.5 Goals in the Full Time Result and U/O 2.5 Goals market. The other World Cup play-off match tonight between Croatia and Greece in Zagreb could end in stalemate as Greece have never lost against Croatia away from home drawing all three previous corresponding fixtures.
