The 2025 season was the first season for San Diego FC in Major League Soccer (MLS), the top flight of professional club soccer in the United States. San Diego FC was announced as an expansion team on May 18, 2023, under the ownership of Egyptian businessman Mohamed Mansour and the Sycuan Band of the Kumeyaay Nation, a local indigenous tribe. The team played their home matches at Snapdragon Stadium, which it shares with San Diego Wave FC of the National Women's Soccer League (NWSL) and the San Diego State Aztecs football team.
Former FC Dallas and United States men's national team assistant coach Mikey Varas was hired as the club's first head coach on September 16, 2024. The 2024 MLS expansion draft took place on December 11, 2024, and allowed San Diego FC to select players from other MLS teams based on eligibility requirements. The team also received the first pick in the 2025 MLS SuperDraft, which took place on December 20, 2024.
The first San Diego FC players, including Designated Player and Mexican forward Hirving "Chucky" Lozano, were sent on loan until they joined the club in January 2025. The club used players from the international Right to Dream academy system and other teams owned by Mansour, including FC Nordsjælland. The first regular season match for San Diego FC was played on February 23 against the LA Galaxy; the team's first home match was March 1 against St. Louis City SC.
The first training sessions for San Diego FC opened on January 13, 2025, two days after the start of the preseason camp. The team practiced at their new training facility, the Sharp HealthCare Performance Center, with most of their expected 2025 roster.
The club's first preseason matches were played behind closed doors against Phoenix Rising FC and Sacramento Republic FC, both from the second-division USL Championship. San Diego FC played in the 2025 Coachella Valley Invitational in February at the Empire Polo Club in Indio, California, and was joined by sister club San Diego Wave FC of the National Women's Soccer League. The team lost 3âÂÂ1 to New York City FC in their first public exhibition match with an opening goal by Paddy McNair and three unanswered from NYCFC. San Diego FC then lost 3âÂÂ0 to the Portland Timbers but defeated the New York Red Bulls 6âÂÂ0 in their final preseason match, which was played with their full starting roster. Members of the team's supporters groups traveled to Indio for the matches.
On February 21, San Diego FC played their inaugural match on the road against the LA Galaxy, the defending MLS Cup champions, at Dignity Health Sports Park in Carson, California. They won 2âÂÂ0 in an upset against the Galaxy with two goals scored by Anders Dreyer; the crowd included an estimated 1,000 San Diego FC supporters who had traveled for the match. The team made their debut at Snapdragon Stadium on March 1 and hosted St. Louis City SC in front of a stadium-record crowd of 34,506. The match finished in a 0âÂÂ0 draw and was marred by the use of a homophobic chant that was condemned by the club and coach Mikey Varas; midfielder Hirving Lozano left early in the first half with a hamstring injury.
The MLS regular season schedule was released on December 19, 2024. Every team will play 34 matches, of which 17 are at home; this includes a full home-and-away series against the fourteen other teams in the Western Conference and six matches against opponents from the Eastern Conference. Unlike previous seasons, play will not be paused for the Leagues Cup in August.
San Diego FC was awarded a berth in the 2025 Leagues Cup that had been forfeited by Vancouver Whitecaps FC due to their participation in the 2025 Canadian Championship and the 2025 CONCACAF Champions Cup.
On January 3, 2025, San Diego FC and Liga MX club Club América announced an agreement to play friendlies at Snapdragon Stadium in 2025 and 2027. The friendly against Club América was moved from June 21 to 7 due to a potential scheduling conflict with the FIFA Club World Cup if América were to qualify.
For the 2025 season, San Diego FC were permitted a maximum of 30 signed players on the first team, of which 10 roster positions were designated for supplemental and reserve players. Additional homegrown players are eligible to be signed to off-roster slots and are able to appear in MLS matches through short-term agreements. The senior players in the first 20 roster positions count towards a base salary cap of $5.95 million with exceptions for certain categories, including up to three Designated Players who counted for a set amount in the cap.
For transfers in, dates listed are when San Diego FC officially signed the player to the roster. Transactions where only the rights to the players are acquired are not listed. For transfers out, dates listed are when San Diego FC officially removed the players from its roster, not when they signed with another club. If a player later signed with another club, his new club will be noted, but the date listed here remains the one when he was officially removed from the San Diego FC roster.
In the 2024 MLS expansion draft, San Diego FC made five selections from a list of eligible players signed with other MLS teams. The club traded away two of their players on the same day as the draft.
