Arsenal midfielder Martin Odegaard admits there was a lot of disappointment after Norway's 0-0 draw with Latvia.
Norway now go to Holland needing to win to be sure of World Cup qualification.
"It is very heavy right now," said Norway captain Ødegaard.
"We are very grateful for the support we receive, so it is unfortunate that we are not able to give them more to cheer for.
"We've put ourselves in a much more difficult situation, we have to be honest about that. But everything is still possible.
"I think we will all be disappointed today. We are allowed to be, so we have to adjust from tomorrow, go to the Netherlands and take three points."
