Cape Town - Romelu
Lukaku became Belgium's all-time record goalscorer with the only goal
of the game as his side beat Japan 1-0 in Brugge on Tuesday night.
The Manchester United striker netted his 31st goal for Belgium with a header from Nacer Chadli's cross in the 72nd minute.
A brace against Mexico last week had seen Lukaku draw level with Bernard Voorhoof and Paul van Himst on 30 goals.
The record-breaking goal came in just his 64th appearance for his country and aged just 24, there is plenty of time for him to score many more goals.
Roberto Martinez’s side extended their unbeaten run to 15 games. Belgium’s last defeat was in a friendly to Spain in September 2016.
In other friendlies, goals from Memphis Depay, Ryan Babel and Luuk de Jong gave the Netherlands a convincing 3-0 win in Romania as the Dutch earned a second win in two since missing out on a place in Russia.
