Kevin De Bruyne provided three first-half assists and then scored himself as Belgium maintained their 100 per cent record in qualifying for Euro 2020 with a comfortable victory in Scotland.
The passing masterclass began in the ninth minute as a devastating counter attack saw De Bruyne pick out Romelu Lukaku for his 26th goal in his last 22 internationals.
That opener came 14 seconds and seven touches after Scotland sent a cross into the Belgium box, and the hosts went two down when De Bruyne's cross was turned in by Thomas Vermaelen.
De Bruyne then made it a hat-trick of assists when his corner was met by Toby Alderweireld, whose header bounced off the bar and in.
Lukaku turned provider for De Bruyne late on, with the midfielder capping a near-perfect display when curling a first-time effort into the far corner.
Belgium now have 18 points in Group I with six wins, while Scotland slip down to fifth after Cyprus won at San Marino. Elsewhere, second-placed Russia secured a late victory against Kazakhstan to edge towards qualification themselves.
