The midfielder scored his 9th goal of the season to keep Colchester United in League One, and stop Preston from sealing automatic promotion.
Ex West Ham United prospect George Moncur wrote himself into Colchester United folklore on Sunday, when he scored the late goal that defeated Preston North End 1-0 and ensured the U's would be playing in League One next season.
The youngster converted Chris Porter's pass in the 82nd minute to consign Preston to the playoffs and pull Colchester out of the relegation zone for the first time since November.
Moncur, the son of Hammers legend John Moncur, only made a couple of appearances in the cups during his time at the Boleyn Ground, instead gathering much of his footballing education through loan spells to Scottish and lower division teams.
One of these loan spells was to Colchester United this season, with the midfielder impressing in the first half of the campaign as he scored 3 times in 17 games for the League One strugglers.
It was enough for the U's to take a punt on signing the 21-year-old permanently, and Moncur has repaid that faith in abundance, scoring another 5 goals as Colchester pulled off an amazing escape from demotion to League Two on the last day of the season.
Though it will be his winner against Preston that will be long remembered, most of Moncur's other strikes have also been key efforts that helped the U's earn points, overturning what was a six-point gap from safety as late as the middle of March.
Considering his youth, it's possible the Hammers could regret letting the former England Under-18 midfielder go, but Colchester for one, will be delighted they did.
