Marcus Rashford is the overnight sensation who is suddenly the striker everybody wants to know more about.
The 18-year-old seized his big chance for Manchester United, stepping in after Anthony Martial tweaked his hamstring in the warm up.
After the game he was greeted warmly by assistant boss Ryan Giggs, who no doubt was imparting a few words of wisdom to the new United hero.
Rashford broke George Best's long standing record to become United's youngest ever goalscorer in European competition.
He could have an important role to play against Arsenal in a few days time, dependent on how quickly Anthony Martial recovers.
He was not the only youngster to impress, with Guillermo Varela and Joe Riley also showing their composure at full-back, and United's youth system suddenly looks like it is producing more young talent than it has done for years.
