Answer
Jose Mourinho, who managed Manchester United from 2016 to 2018, gave Scott McTominay his senior debut in May 2017. Mourinho was impressed by McTominay's performances for the club's youth team and reserves, and he handed the young midfielder his first-team debut in a Premier League match against Arsenal. McTominay has since become a regular member of the Manchester United squad, and he has made over 100 appearances for the club.
