United captain Harry Maguire posed for images with fans pitchside ahead of kick-off and spoke to MUTV before the young Reds played in front of a record 60,000-plus crowd.
Cameras spotted David De Gea in the crowd in the first half, along with defenders Phil Jones and Eric Bailly.
Midfielders Bruno Fernandes and Scott McTominay were also in attendance at the Theatre of Dreams, with the former issuing a message of support for the young Reds on Twitter this morning.
This isn’t the first time that our first team players have publicly backed United’s youth teams, as Maguire also made an appearance at the Under-19s' UEFA Youth League round-of-16 against Borussia Dortmund in March and the Youth Cup semi-final against Wolves in the same month.
