World Cup 2026: Iran vs. Belgium Odds, Best Bets & Prediction

Betway odds, current at time of writing and subject to change without notice.

Both level on a point each, Iran and Belgium meet on June 21.

Group G opened with two draws: Belgium were held 1-1 by Egypt, and Iran shared the points in a 2-2 stalemate with New Zealand. With Egypt and New Zealand meeting in the other matchday-two fixture, both Belgium and Iran have effectively transformed this into a de facto elimination game. Lose here, and either team faces a final group match requiring a result against a side that has already accumulated points.

Belgium arrive as firm favorites but carry significant fitness concerns at the most important positions. Kevin De Bruyne has been managing a knock that has limited him to around 80% capacity, and Romelu Lukaku has accumulated barely  60 competitive minutes all season, despite scoring 22 seconds after coming on against Egypt. Iran, stripped of Sardar Azmoun for non-sporting reasons, rely almost entirely on Mehdi Taremi's individual quality to create a threat.

The Iran side

Amir Ghalenoei has built a team defined by defensive resilience and collective organization. The 2-2 draw with New Zealand was a display of character more than quality: Iran came from behind twice and showed the mental fortitude their system requires. The defensive structure is compact and disciplined, built around a two-bank-of-four that reduces the space available to technically superior opponents and forces them into wide areas rather than central pockets.

Without Azmoun, Iran's attacking options are critically limited in this fixture. Taremi will face Belgium's organized back four without the movement and pace that Azmoun would have provided alongside him. Mehdi Ghayedi and Ali Gholizadeh need to contribute more than they managed against New Zealand if Iran are to create genuine chances. The match profile points to a team that will defend with nine or ten players and looks for one Taremi moment to score.

Team news: Azmoun is absent for non-sporting reasons. Taremi confirmed to start despite carrying a minor knock from the opening match.

Probable lineup Iran (4-3-3): Beiranvand; Moharrami, Hosseini, Pouraliganji, Hajsafi; Ezatolahi, Nourollahi, Ghayedi; Sayyadmanesh, Taremi, Gholizadeh.

The Belgium side

Belgium drew 1-1 with Egypt in a performance that confirmed both their individual quality and their collective limitations against organized defenses. De Bruyne at 80% fitness is still more effective than most midfielders at full capacity, and his ability to control tempo and strike from distance gives Belgium a consistent threat in even the most compact games. Doku's directness on the right provided a consistent source of problems for Egypt and should create similar difficulties against Iran's narrower defensive block.

The Lukaku question defines Belgium's tactical approach. His minutes were limited all season before scoring as a substitute against Egypt. Starting him from the beginning risks a significant drop in performance level after the hour mark. Starting Openda or a fresher option makes more tactical sense for a ninety-minute performance, but Lukaku's proven quality in pressure moments is difficult to leave on the bench in a must-win game. With Group G still entirely open heading into matchday two, the decision could define Belgium's tournament.

Team news: De Bruyne expected to start despite fitness management. Lukaku's starting position is uncertain given his limited minutes all season.

Probable lineup Belgium (4-2-3-1): Casteels; Castagne, Debast, Faes, Theate; Onana, Tielemans; Doku, De Bruyne, Trossard; Lukaku.

Betway and 888sport odds, correct at the time of writing

Belgium are the stronger team and face an Iran side missing its second most reliable attacker. The quality gap should ultimately determine the result, even if Belgium's fitness concerns mean the performance will not be entirely convincing. We predict Belgium 2-0 Iran, with both goals in the second half as Iran's organized defensive block holds initially before Belgium's individual quality proves decisive.

The market prices Belgium at approximately 66% implied probability of victory at -250. Our estimate of 60% is more conservative: De Bruyne at 80% fitness, Lukaku's match-sharpness deficit, and Iran's demonstrated resilience under pressure all suggest that a 66% probability overstates Belgium's current output capacity.

The implied probability of the Over 2.5 Goals market at -110 is approximately 52%; our estimate sits closer to 44% to 48%. Iran will defend with nine or ten players and Taremi alone is unlikely to generate a multi-goal output from the Iranian side. Belgium scored once against Egypt in a match where they created clear chances. The absence of Azmoun is a decisive factor in keeping this total low.

Under 2.5 Goals: -111

Belgium's defensive record, combined with Iran's limited offensive output without Azmoun, makes Under 2.5 Goals the cleaner value in this fixture. Iran are built to absorb and counter, meaning multiple goals from their side requires a Belgium defensive error rather than systematic attacking quality. Belgium scored once against Egypt in a match with clear quality dominance. At -111, Under 2.5 Goals offers a near-even proposition that the match profile fully supports as a lean toward the lower total.
