"We have had some hammer blows and this is the latest one," said Levein.
"We have got an honest, hard-working group of boys who feel a bit aggrieved about what happened and we will try to use that for Tuesday.

Fifth-placed Scotland go into the match against Belgium five points behind the Group A leaders.
