Joseph Colley is a defender currently playing in Chelsea's Academy team.
Joseph came through the ranks at Brommapojkarna in Sweden.
Joseph joined Chelsea on a scholarship in July 2015 after spending the previous year intermittently on trial at the club. Quickly establishing himself as a powerful and versatile defender with authority and technique to spare, he proved himself a reliable and dependable option for Joe Edwards in the league campaign whilst contributing when needed in the 2015-16 FA Youth Cup and 2015-16 UEFA Youth League successes. Despite being just 16, he also progressed into Under-21 football early, finishing the season with three appearances to his name.
He split the 2016-17 season between both age groups, splitting his 31 appearances in all competitions almost perfectly equally. He started the season with Adi Viveash's Development Squad, experiencing some ups and downs, whilst also joining Jody Morris' youth team for league and cup duties, eventually claiming winners' medals in both as he said farewell to Under-18 football.
Joseph has represented Sweden up to Under-19 level, regularly serving as the team's captain.
