Jorge Alvial has left his role as international scout at United to take up a new post with FC Cincinnati.
The Chilean previously worked with Jose Mourinho at Chelsea and followed the 55-year-old to Old Trafford in 2016 after the United boss recommended him for the role.
During his time at United, Alvial was responsible for finding elite players in the Americas who could play for the first team, particularly those aged between 17 and 24.
Of course, his compatriot, Alexis Sanchez, arrived while Alvial was working at United and the 29-year-old had been repeatedly recommended to Mourinho during their spell together at Chelsea.
In 2006, Alvial earmarked the Cobreloa youngster as a prospect for the future and, in 2013, Chelsea were interested in the Chilean before he joined Barcelona from Udinese.
Alvial has left United to become head of scouting with FC Cincinnati – who will begin playing in Major League Soccer next year. The talent spotter has previously worked at Sporting Kansas City and Atlanta United so knows the territory well but it is a blow for Mourinho.
The United boss has already lost one ally, assistant Rui Faria, who also followed him from Chelsea and the club will now be on the lookout for a new international scout.
In the last few months, United have advertised for a new scout in France, a recruitment analyst and a scouting administrator.
