The attacking midfielder won the FA Youth Cup on two occasions with the Blues, but only made one first team appearance for the club amid seven loan spells.
Brown was once tipped by Jose Mourinho as a certainty to play for England, alongside Dominic Solanke and Lewis Baker, with the former Chelsea boss insisting the media should ‘blame him’ if they didn’t make it.
Three members of Chelsea side which overcame Manchester City 5-2 over two legs in the 2015 FA Youth Cup final, which featured Brown and Solanke, have since featured for the Three Lions.
Sportsmail takes a look to see where members of the squad are now following Brown’s retirement.
Goalkeeper – Bradley Collins
Collins was the Blues goalkeeper for the two-legged final, conceding to Isaac Buckley-Ricketts in the 3-1 first leg win before being beaten by Kelechi Iheanacho in the 2-1 triumph in the second.
The goalkeeper was part of the Chelsea side that lifted the UEFA Youth League in the same season.
