World Cup semi-finalists Belgium capitalised on a series of Scotland mistakes with goals from Romelu Lukaku, Eden Hazard and a Michy Batshuayi double to thrash the hosts 4-0 in a friendly at Hampden on Friday.
Roberto Martinez's men showed their class and no hangover from their exertions in finishing third in Russia to warm-up for their Nations League opener against Iceland on Tuesday.
However, the visitors were handed a series of gifts by a Scotland side that slumped to a fourth defeat in five games since manager Alex McLeish was appointed for a second spell in charge.
"We were very clinical in front of goal," said Martinez. "The players were well focused overall and for us it was a good excercise for Tuesday."
"It's harsh lessons, big lessons for the young ones especially, but they should not be downhearted as they were up against a top team."
