Both teams had already qualified to the Round of 16 so all that was left was to decide who was going through in first and who was going through in second.
England were leading the tie going into the match thanks to the yellow card rule but that all changed in the 51st minute.
Januzaj cut in from the right, dropped a shoulder to waltz past Danny Rose before curling an unstoppable shot across Jordan Pickford and into the top left corner to make it 1-0 to Belgium.
The quality of the goal stunned the stadium with the 'Red Devils' surrounding the former Manchester United forward in jubliant celebration.
