2018 (D.C. United): In his season with the Black-and-Red, Frederic Brillant was a mainstay at center back after making 27 appearances (24 starts) in the regular season. Brillant collected his first point for the Black-and-Red on March 17, assisting Luciano Acosta’s 96th-minute equalizer against the Houston Dynamo. His first goal for the club came on November 1 in the knockout round of the Audi 2018 MLS Cup Playoffs against the Columbus Crew. Brillant’s close-range header opened the scoring, and marked the first playoff goal for the Black-and-Red at Audi Field.
2017 (NYCFC): In 2017, Brillant continued to be a key factor in the New York defense, making 23 appearances and scoring one goal. His lone goal that year was as an important game-winner in the 2-1 win against second place Chicago on July 22. His defensive ability helped pave the way for New York to have the fifth stingiest defense in MLS (third in Eastern Conference) by allowing only 43 goals in 2017.
2016 (NYCFC): Brillant made his MLS debut in a win over Chicago on March 6, 2016 and became a mainstay in the NYCFC backline that season. He started 31 out of 34 regular season games for the Sky Blues and helped lead the franchise to their first ever MLS Cup Playoff berth. The defender recorded eight shutouts in his first season and scored his first career MLS goal on May 29, 2016 in a 2-2 draw with Orlando to earn an MLS Team of the Week selection. His performance in October of that year earned him the Etihad Player of the Month award for NYCFC.
2011-2016 (Koninklijke Voetbalclub Oostende / Koninklijke Beerschot Antwerpen Club): Brillant started his professional career in the Belgian First Division with Koninklijke Voetbalclub Oostende.

He spent the 2012/2013 season with Koninklijke Beerschot Antwerpen Club and made 32 appearances, scoring one goal and recording three assists.
