When these four former footballers started out their careers with a twinkle in their eyes and luscious locks, it would have been hard to imagine them taking the helm of some of Europe's most elite clubs.
One manager currently in charge of one of the most successful teams in history looks unrecognisable with a windswept quiff on his head, while a grey-haired manager with both Premier League and international experience resembles a completely new person with marvellous long, curly locks.
Another manager to lose their hair in management was once capable of growing out extraordinary ginger locks and a Premier League-winning boss used to don a magnificent short yet incredibly stylish haircut during his playing days.
