Why did JJ Gabriel ask to leave Manchester United?

Manchester United has gotten off to a rocky 1-1-2 start this season and is now dealing with internal turmoil. JJ Gabriel, Manchester United's Under-18 player of the year, has formally requested to leave the club, according to BBC's Simon Stone.

The decision came as a shock to both soccer fans and Manchester United. Gabriel, 15, made his senior debut in last month's preseason game against Atletico Madrid, and he was expected to play Wednesday against Brighton in the Carabao Cup. Just last week Gabriel scored a hat-trick in his Uefa Youth League debut, and he's scored twice over two games for United's Under-21 team in Premier League 2.
