Richie Williams’s tenure as head coach of D.C. United’s new second-division team lasted less than half the season.
Williams, a former D.C. midfielder who accepted the job in January, is leaving Loudoun United to join Bruce Arena’s staff at the New England Revolution, effective immediately.
Williams and Arena have a long history, starting at the University of Virginia in the 1980s and continuing in MLS and the U.S. national team. Arena last week was appointed New England coach last week and has begun building his staff.
Curt Onalfo, a former D.C. player, assistant and head coach who also has deep ties with Arena, is expected to become New England’s technical director.
