DR Congo vs Portugal

Portugal begin their tournament against a DR Congo side carrying the weight of an entire region's hopes — no nation from Central Africa has reached a World Cup knockout round since Cameroon in 2014. That context matters because the Leopards possess genuine quality: Chancel Mbemba marshals a defence that conceded just four goals in the final round of CAF qualifying, while Yoane Wissa's direct running from wide positions gives them a credible outlet in transition. The problem is that Portugal represent arguably the most complete squad in the tournament.

Roberto Martínez has settled on a system that accommodates Bruno Fernandes as the primary creator, with Rafael Leão offering explosive width on the left and a deep bench that includes João Félix and Diogo Jota — players who would start for most nations here. These teams have never met competitively, though a 2014 friendly in Lisbon ended 5-1 to Portugal, a result that flattered the hosts but exposed the gulf in squad depth. DR Congo's best chance lies in disrupting Portugal's rhythm early, pressing Fernandes before he can turn and face forward, and exploiting the space behind Leão when the wing-back bombs on. Mbemba's experience against European opponents from his time at Porto and Marseille means he will not be overawed.

An upset remains unlikely, but if Congo can keep the match goalless at half-time, tension will creep into Portuguese play.
