A 20-year-old South African defender, Mbekezeli Mbokazi, joins the Fire to add left-footed depth and versatility, capable of partnering with Jack Elliott and Joel Waterman across varying formations.

Christopher Cupps, a 17-year-old homegrown defender, is vying for minutes as Berhalter targets double-digit first-team appearances in 2026, continuing his progression from U-17 World Cup captain to MLS influence.

In 2026, the Fire will compete on three fronts—MLS, the U.S. Open Cup, and the Leagues Cup—creating fixture congestion but also opportunities to rotate the backline and develop young players like Cupps.

Head coach Gregg Berhalter continued the theme of defensive experimentation, keeping a back three in play at times in 2025 and planning further formation flexibility into 2026 to boost stability and set-piece effectiveness.

The broader plan emphasizes tactical flexibility between back fours and back threes, using Mbokazi and rising talent Cupps to build a versatile, depth-rich defense adaptable to opponents.

Chicago Fire have transformed their center-back group from a 2025 weakness into a strength for 2026 through new signings and strategic shifts.

Mbokazi is viewed as a potential starter who can slot in at left center-back in both back three and back four systems, with his Africa Cup of Nations performances and a multi-million-dollar U-22 initiative deal underscoring his high potential.
