The Newest MLS Team: San Diego FC Joins in 2025
San Diego FC is the newest MLS team. Their path to the league, stadium plans, roster building strategy, and what to expect in 2025.
San Diego FC is the newest team in Major League Soccer, having entered the league as the 30th franchise in 2025. Backed by Egyptian billionaire Mohamed Mansour and the Sycuan Band of the Kumeyaay Nation, San Diego FC brings MLS to one of the largest metropolitan areas in the United States -- a market of 3.3 million people that has long been considered overdue for top-flight professional soccer.
The club's arrival caps a multi-year expansion push that has transformed MLS from a 24-team league in 2020 to a 30-team league in 2025. For the full story of how MLS has grown and where it is headed next, see our comprehensive guide to MLS expansion.
The Path to MLS
San Diego's journey to an MLS franchise was neither quick nor straightforward. The market had been discussed as an expansion candidate for years, but several earlier attempts fell short.
Early Bids and False Starts
San Diego appeared on MLS's expansion radar as early as 2017, when the league announced it would expand beyond 24 teams. However, early bids faced a recurring obstacle: stadium plans. MLS has made soccer-specific stadiums (or exclusive stadium arrangements) a virtual requirement for expansion, and San Diego's initial proposals struggled to identify a viable site and funding model.
The market's appeal was never in question. San Diego sits on the U.S.-Mexico border, with deep cultural ties to soccer through its large Latino population and proximity to Tijuana (home to Club Tijuana of Liga MX). Youth soccer participation in the San Diego area is among the highest in the country, and the region's climate allows year-round play.
The Winning Bid
The ownership group that ultimately secured the franchise came together around several key elements:
Ownership: The Mansour Group, led by Egyptian billionaire Mohamed Mansour, provided the financial foundation. Mansour's net worth exceeds $7 billion, making him one of the wealthiest MLS owners. The ownership group also includes the Sycuan Band of the Kumeyaay Nation, marking one of the first Native American tribal partnerships in major North American professional sports.
Stadium commitment: The ownership group committed to building a 35,000-seat soccer-specific stadium in the Midway District of San Diego, near the intersection of Interstate 8 and Rosecrans Street. The location provides accessibility from across the metropolitan area and proximity to downtown.
Expansion fee: San Diego FC paid a reported $400 million expansion fee, the highest in MLS history, reflecting the league's surging franchise valuations and the desirability of the San Diego market. For context on how this fee compares to previous expansion costs, see our detailed breakdown of MLS expansion fees.
MLS Approval
MLS officially announced San Diego as the league's 30th team in May 2023. Commissioner Don Garber cited the ownership group's financial strength, stadium plans, and the market's demographics and soccer culture as deciding factors. The announcement came alongside a commitment to begin play in 2025, giving the organization roughly two years to build a front office, hire coaching staff, develop a brand identity, and construct a roster from scratch.
Stadium Plans
The stadium is a centerpiece of the San Diego FC project and represents one of the most ambitious sports venue developments in the region's history.
Right to Dream Park
San Diego FC's stadium, named Right to Dream Park through a partnership with the Right to Dream global soccer development network, is planned as a state-of-the-art soccer-specific venue.
Key specifications:
- Capacity: Approximately 35,000 seats, expandable for major events
- Location: Midway District, San Diego
- Design: Open-air with canopy coverage, designed for Southern California's climate
- Features: Safe-standing supporter section, premium hospitality areas, integrated public spaces
- Cost: Estimated at over $500 million in private funding (no public stadium subsidies)
The privately funded model is significant. Many MLS stadiums have relied on some form of public financing, but San Diego FC's ownership committed to fully private funding, which helped win political support in a city that has historically been skeptical of taxpayer-funded sports venues.
Interim Venue
While the permanent stadium is under construction, San Diego FC played its inaugural 2025 season at Snapdragon Stadium, the 35,000-seat venue at San Diego State University that opened in 2022. Snapdragon serves as a functional interim home, though its football-first design is not optimal for soccer sightlines. The club plans to move into Right to Dream Park once construction is completed, targeted for 2027 or 2028.
Roster Building Strategy
Building an MLS roster from scratch is a complex process governed by expansion draft rules, salary cap constraints, and the transfer market. San Diego FC's approach has reflected a blend of experience, youth, and strategic spending.
Expansion Draft
Like all new MLS teams, San Diego FC participated in an expansion draft in which they could select unprotected players from existing clubs. Each existing team was allowed to protect a set number of players (typically 12 from senior rosters), and San Diego could select up to five players.
The expansion draft provides a foundation of MLS-experienced players, though the available talent is, by design, not the best from any given roster. Clubs protect their stars, so expansion draft picks tend to be solid role players, aging veterans, or young prospects blocked from playing time elsewhere.
Designated Player Signings
San Diego FC's DP strategy has been closely watched, as marquee signings set the tone for a new franchise's ambitions. The club has targeted a mix of proven international talent and high-upside younger players for their three DP slots.
The club's approach contrasts with some recent expansion teams that spent heavily on aging international stars (Inter Miami's early DP signings before Lionel Messi) versus those that invested in younger, transfer-value assets (St. Louis City SC's model). San Diego has reportedly sought players in the 24-29 age range who can be both on-field difference-makers and potential future transfer sales.
Academy and Homegrown Pipeline
San Diego FC has invested in establishing an academy system from day one, recognizing that long-term MLS success increasingly depends on homegrown player development. The San Diego area is rich with youth soccer talent, and the club aims to create a pipeline from local youth leagues through MLS NEXT Pro (the league's second division) to the first team.
The club's connection to the Right to Dream network -- a global soccer development organization with academies in Ghana, Denmark, and Egypt -- provides an international scouting and development infrastructure that most expansion teams do not have at launch. This partnership could give San Diego FC access to young international talent through established development pathways.
Key Early Signings
While the full roster continues to evolve through San Diego FC's inaugural season, the club has made several notable acquisitions:
- Multiple international signings from South American and European markets
- Strategic expansion draft selections focused on MLS experience and defensive stability
- Homegrown signings from the Southern California talent pool
- U-22 Initiative signings targeting young players with transfer-value upside
The Coaching Staff
San Diego FC's choice of head coach was a statement about the club's ambitions. The club hired a coaching staff with experience across MLS and international competition, emphasizing tactical sophistication and player development.
The coaching philosophy reportedly emphasizes possession-based soccer, high pressing, and integration of young players -- a style consistent with the most successful recent MLS expansion launches (Atlanta United, LAFC, St. Louis City SC).
The San Diego Market
San Diego FC enters a market with significant advantages and a few challenges.
Advantages
Demographics: San Diego County's population of 3.3 million includes a large Latino community with deep soccer roots. The border proximity to Tijuana means many residents already follow Liga MX and international soccer, creating a built-in fan base that understands and values the sport.
Climate: Year-round pleasant weather eliminates the attendance challenges that cold-weather MLS markets face during early and late-season matches.
No direct competition: San Diego has not had a major professional men's outdoor team since the NFL's Chargers left for Los Angeles in 2017. While the Padres (MLB) remain popular, MLS will not compete directly with another outdoor fall/spring sport for attention.
2026 World Cup: San Diego is not a host city for the 2026 FIFA World Cup, but its proximity to host cities (Los Angeles, potentially others) means the region will experience significant World Cup energy, which could boost interest in MLS.
Youth soccer culture: San Diego consistently ranks among the top metropolitan areas for youth soccer participation, providing both a fan development pipeline and a player development resource.
Challenges
Expansion team growing pains: Every new MLS franchise faces an adjustment period. On-field results in year one are typically inconsistent, and fan patience can be tested. Recent expansion teams have had mixed inaugural seasons -- St. Louis City SC made the playoffs in year one, while others have struggled.
Stadium timeline: Playing in an interim venue while the permanent stadium is built creates a less-than-ideal fan experience. The transition period requires maintaining enthusiasm without the full matchday experience that a soccer-specific stadium provides.
Regional competition: While there is no direct MLS competitor, San Diego fans have access to Liga MX matches in Tijuana (a short border crossing away) and LAFC and LA Galaxy matches three hours north. Capturing the region's soccer fans requires demonstrating that MLS provides a compelling live product.
San Diego FC in the Context of MLS Expansion
San Diego FC's entry at the $400 million fee level represents the current peak of MLS expansion economics. As the 30th team in MLS, the club arrives at a moment when the league is transitioning from rapid expansion to potential consolidation. MLS has discussed growing to 32 teams, but the timeline and markets for teams 31 and 32 remain unclear.
For the league, San Diego checks every box: a large market, wealthy ownership, a stadium plan, a soccer-passionate demographic, and a willingness to pay a record fee. If San Diego FC succeeds -- on the field and at the gate -- it validates the $400 million+ price tag and supports even higher fees for future expansion.

San Diego FC's Second Season: 2026
Now entering the 2026 season, San Diego FC looks to build on the foundations laid during their inaugural 2025 campaign. Key storylines heading into year two include:
- Roster maturation: How the club's Designated Player signings and expansion draft picks have settled in after a full season of MLS experience
- Attendance trends: Whether San Diego can sustain and grow the strong fan interest established during their debut year
- Playoff contention: With a season of MLS experience under their belt, the club is better positioned to compete for a postseason spot
- Stadium progress: Updates on the permanent Right to Dream Park venue, which remains a critical long-term project
Key Takeaways
San Diego FC is the newest and most expensive expansion franchise in MLS history. The club brings the league to a major border market with deep soccer culture, backed by a billionaire ownership group and an ambitious stadium project. Whether San Diego FC becomes the next Atlanta United (immediate success) or follows the slower path of earlier expansion teams will depend on roster construction, coaching, and the community's embrace of MLS soccer.
