Ole Gunnar Solskjaer tipped Shola Shoretire for a bright future after the 17-year-old came on against Real Sociedad and became Manchester United's youngest-ever player in European competition.
Having secured a surprisingly comprehensive 4-0 win in last week's first leg in Turin, the Red Devils knew progress from the round of 32 was all but assured heading into the return fixture at Old Trafford.
United and Sociedad played out a forgettable 0-0 draw in the second leg, but Thursday's match will go down in the history books after Shoretire's record-breaking late introduction.
Having made his debut as a substitute in Sunday's league win against Newcastle, he replaced Norman Whiteside as the youngest player to represent United in European competition by coming on aged 17 years 23 days.
