The defeat left Craig Levein’s side sitting above only Macedonia on the Group A table with two points from three outings and Morrison feels victory from Tuesday’s meeting with group leaders Belgium in Brussels is absolutely essential.
"There is probably a little bit of hope if we win in Belgium,” he said.
“We get that belief again and that's all we can do. We've got to regroup quickly or else the group is going to pass us by.
"Basically, we've got to win in Belgium. We've just got to remain positive, that's all we can do.”
