Belgium vs Iran: Under 2.5 goals worth backing

The bookmakers have looked at Iran's 2-2 draw with New Zealand and Belgium's galaxy of stars and immediately leaned toward an open, high-scoring match. But that surface-level read ignores the most important factor in this World Cup Group G clash: Iran's tactical shift to a compact 5-4-1 low block, combined with Belgium's loss of their most dangerous wide attacker. The value sits firmly with Under 2.5 goals.

Iran's defensive fortress

Coach Amir Ghalenoei has made no secret of his game plan. After seeing his side concede twice to New Zealand—one from a direct physical duel and another from a cross—he will drop his block even deeper, congesting the central channels and forcing Belgium to attempt crosses from wide areas. Iran's five-man defensive line, with three centre-backs, is tailor-made to nullify a lone striker like De Ketelaere or even the later introduction of Lukaku.

Iran have no intention of dominating possession. Their only attacking ambition is to survive, break up play, and hit Belgium on the counter through Mehdi Taremi's hold-up play and the right-sided delivery of Ramin Rezaeian. They will happily let Belgium have 65% of the ball in non-threatening areas.

Belgium's missing dagger

Jérémy Doku is out of the matchday squad with a worsening respiratory infection—a hammer blow for Belgium's ability to break down a deep block. Doku is their only pure 1v1 dribbler, the one player who can take on two or three defenders and create chaos. Without him, the attack becomes more predictable: full-back overlaps, crosses from Saelemaekers and Trossard cutting inside, and reliance on De Bruyne's through balls against three centre-backs.

Romelu Lukaku is still not considered fit enough to start, so Belgium will begin with De Ketelaere as a mobile No.9. He is clever with his movement, but he cannot physically dominate central defenders the way Lukaku can. Belgium's possession may be sterile, with Iran content to absorb pressure and clear crosses.

Form and tournament tension

Belgium laboured to a 1-1 draw with Egypt in their opener, looking short of rhythm and sharpness. Their best attacking moments came from set-pieces and a forced own goal, not slick combination play. Iran, meanwhile, showed character to come from behind twice against New Zealand, but they also demonstrated worrying defensive vulnerability on the break—something Belgium can exploit, but not consistently without Doku.

The group is tight: all four teams have one point. A draw is not a disaster for either side, but Belgium need a win to avoid pressure heading into the final matchday. That urgency could lead to frustration if the goal doesn't arrive early, potentially resulting in a nervy, low-quality affair.

Travel, fatigue and mentality

Iran have been dealt a poor logistical hand. They were forced to leave the USA quickly after the New Zealand game, had minimal recovery time and less than 16 hours on-site preparation before this match. Ghalenoei has complained publicly about the unfair scheduling, which can be used as motivation but also disrupts normal pre-match routines and physical readiness.

Belgium, by contrast, moved smoothly from Seattle to Los Angeles and had a full training window. Yet even with the advantage, they face a side that will sit deep, commit tactical fouls, and slow the game to a crawl. The combination of a stifling defensive structure, a key attacking absence, and the tournament stakes points firmly toward a low-scoring outcome.
