Conor Gallagher went from being an eight-year-old Chelsea academy signing to wearing the captain's armband.
Yet his 16-year spell at the club he grew up supporting is over following the England midfielder's move to Atletico Madrid for about £33m.
Some Chelsea supporters are upset at the 24-year-old's departure, claiming homegrown Gallagher's exit increases the gulf between the ownership and the fanbase.
Others appear fine with it, external and believe the money for a player who was out of contract next summer will help balance the books.
While the debate among fans goes on, Gallagher is beginning the next chapter of his career in Spain where he faces a showdown with England team-mate Jude Bellingham on 29 September when Atletico host Real Madrid in La Liga.
