Scotland boss Craig Levein has urged his players to react "in the right manner" when they face Belgium in Brussels on Tuesday.

The Tartan Army were furious with the linesman's decision to disallow them a goal in Friday's 2-1 World Cup qualifying defeat to Wales in Cardiff.

"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.

"The only we thing we can do is go to Belgium and try to win the game. I feel an injustice but the important thing is that we react in the right manner."

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