After seeing a young George Best in action, scout Bob Bishop sent a telegram to then-Manchester United manager Matt Busby that famously read: "Boss, I think I’ve found you a genius."
Boy, was Bishop right.
The Red Devils signed Best and, despite a busy lifestyle off the pitch, the Northern Irishman became an all-time great at Old Trafford.
These days, of course, scouts don't need to send telegrams to tell a club they've spotted a player with potential.
Whatever method of communication they do use, Manchester United's scouting network in Mexico has alerted the club about the talents of Hirving Lozano.
