United beat Real Madrid 3-0 on penalties to secure 5th place in the Blue Stars FIFA Youth Cup in Zurich on Thursday.
The prestigious tournament in Switzerland pits some of the best young players in the world against each other in games of two halves of 20 minutes.
United were drawn in Group B with Swiss sides FC Basel, FC Blue Stars, Brazilians Flamengo, and Turkish outfit Fenerbahce.
On Wednesday, the Reds beat FC Blue Stars 2-0, with goals from Febian Brandy and Josh King. Next up for United were Fenerbahce, who proved slightly tougher opponents. Rodrigo Possebon and Brandy twice gave the Reds the lead, but each time the Turkish youngsters levelled.
United's final match that day was against last season's runners-up, FC Basel. The Swiss side took the lead before Possebon equalised, but then Basel turned on the style, hitting four goals to run out 5-1 winners.
The Reds' last group game, on Thursday morning, saw the Reds draw 1-1 with Brazilian club Flamengo, setting up a 5th-6th place play-off with Real Madrid.
The clash ended 0-0 at full-time, but Oliver Norwood, Possebon and Brandy all converted without reply from Real to clinch victory.
