Craig Levein has urged his Scotland players to draw on their sense of injustice about defeat to Wales when they take on Belgium.
A first-half opener from James Morrison put the Scots on course for their first World Cup qualifying Group A win in Cardiff until Gareth Bale struck a late double.
Levein was left to rue the Steven Fletcher goal that was chalked off 15 minutes from time with his side still leading but the boss has swiftly turned his attention to Tuesday's night's must-win game in Brussels.
Levein said: "We have had some hammer blows and this is the latest one.
"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.
"We all know the game is finished now and whether the officials have made one, two or three mistakes, it is not going to help us. We need to win in Belgium now."
