This is one of those games that will be very tight until the first goal is scored, if it is at all. Depending when that happens will play a huge role in the rest of the game. This match is huge for both sides and everything is on the line so they will throw caution to the wind to win.
New Zealand have a good defense but offensively they are ineffective and pose no threat, Bahrain are an interesting team, they play better than you would think, defensively not as good as New Zealand but they are a much more potent threat going forward.
This isn't a game to go crazy on but I'd give the edge to Bahrain +0.5 or Under2.5
