Cowley and his younger brother Nicky - who will be Huddersfield's manager and assistant boss respectively - grew up as West Ham fans.
The pair - both ex-PE teachers - played together at Romford and later joined forces in the dugout of Concord Rangers, before moving to Lincoln City via a brief spell at Braintree Town in 2016.
Two promotions and a Football League Trophy later, the Cowleys have found themselves in demand from higher division clubs.
And having already turned down moves to West Bromwich Albion and Hull City, according to The Daily Mail, they have finally left Sincil Bank for Huddersfield, having also had interest from Sheffield Wednesday.
But given their ascent so far, Huddersfield might not be the last stop on the Cowleys' managerial tour.
And the following West Ham fans feel that a stint at the London Stadium could beckon...
Danny Cowley is some appointment by Huddersfield. Don’t think there’s been a manager in world football with more promotions than him in the last 10 seasons. Hopefully it’s the stepping stone to the West Ham job in a few years.— Jordan Sayward-jones (@jsaywardjones) September 9, 2019
