Lille FC forward Divock Origi made his Belgium debut on Monday night in the Red Devils' rampant win over Luxembourg, with Chelsea striker Romelu Lukaku bagging a hat-trick.
Origi, 19, and son of Kenyan international Mike Okoth, was brought in on the hour mark replacing Lukaku while Manchester United youngster Adnan Januzaj made his international debut as a substitute in Monday's victory.
Belgium have been drawn alongside Algeria, Russia and South Korea in Group H at next month's World Cup. Lukaku opened the scoring after three minutes, finishing well after being teed up by Marouane Fellaini.
Joachim equalised from long-range for Luxembourg on 13 minutes, but Lukaku regained Belgian's lead 10 minutes later after a defensive mix-up. United star Januzaj made his debut, coming on at half-time as Marc Wilmots ringed the changes, with Vincent Kompany and Eden Hazard rested among others.
And Lukaku, who was on loan at Everton last season, sealed his treble by running past two defenders and driving low into the net.
Tottenham's Nacer Chadli added a fourth, finishing well after good work by the hosts down the right. And the Premier League dominance shone through again, with former Chelsea man Kevin De Bruyne slotting home a penalty late on to complete the rout.
