Momentum is a powerful thing at the FIFA World Cup, and both Belgium and Senegal head into Wednesday’s Round of 32 clash in Seattle hoping to build on emphatic Matchday 3 victories. Belgium topped Group G after a commanding win over New Zealand, while Senegal booked their place in the knockout rounds with a five-goal demolition of Iraq. Now, both sides are chasing a place in the last 16.

The Opta supercomputer makes Belgium favourites, but not by an overwhelming margin. Across 25,000 pre-match simulations, Belgium won inside 90 minutes in 45.6% of outcomes. Senegal claimed victory in 27.0% of the simulations, while 27.4% ended level after normal time. Factoring in extra time and penalties, Belgium have a 59.0% chance of progressing to the Round of 16, compared to Senegal’s 41.0%.

Senegal’s tournament looked to be slipping away after defeats to France and Norway in Group I, but Pape Thiaw’s side responded in spectacular fashion. Their 5-0 victory over Iraq secured qualification as one of the best third-placed teams and produced their most complete performance of the competition.

Against Iraq, Senegal recorded 28 shots, 12 efforts on target, an expected goals (xG) total of 3.01 and 51 touches inside the opposition penalty area. All four were their highest figures in a World Cup match and provided the attacking blueprint Thiaw will hope to replicate against Belgium.

A major factor behind that resurgence has been the form of Ismaïla Sarr. Having seemingly overtaken Nicolas Jackson as Senegal’s preferred central striker, Sarr has been directly involved in four goals at this tournament, scoring three and providing one assist. That equals the highest goal involvement by a Senegal player at a single World Cup, matching Henri Camara’s four contributions during the nation’s memorable run in 2002.

Behind him, Idrissa Gueye continues to dictate play from midfield. The experienced Everton midfielder completed 39 line-breaking passes during the group stage, comfortably the highest total among Senegal players. His ability to progress possession has become something of a trademark. At the 2025 Africa Cup of Nations, he also led the entire tournament with 100 line-breaking passes.

While Senegal’s attack has flourished, defensive concerns remain. Their three group-stage matches have produced a combined 14 goals, with eight scored and six conceded. Only Norway’s games, which featured 15 goals, have seen more action during the group stage.

History also presents another obstacle. Senegal are searching for only their second knockout-stage victory at the FIFA World Cup. Since defeating Sweden 2-1 after extra time in the Round of 16 in 2002, they have lost both of their knockout matches without scoring, falling 1-0 to Türkiye in the quarter-finals later that year before suffering a 3-0 defeat to England in the Round of 16 at Qatar 2022.

Belgium arrive with a very different story. Rudi Garcia’s side are unbeaten in their last 16 matches across all competitions, winning 10 and drawing six, although their route to the top of Group G was anything but straightforward.

After opening the tournament with consecutive draws against Egypt and Iran, Belgium became the first nation since the United States in 2010 to finish top of their World Cup group despite failing to win either of their opening two matches. They are also the first European team to achieve that feat since England at Italia ’90.

Their 5-1 victory over New Zealand on Matchday 3 transformed the complexion of the group. The result secured first place on goal difference ahead of Egypt and represented Belgium’s biggest victory in World Cup history. Remarkably, they scored more goals in that single match than they had managed across their previous seven World Cup fixtures combined.

Leandro Trossard was one of the standout performers, scoring twice while continuing to establish himself as one of the tournament’s most creative players. The Arsenal forward has created 13 chances during the group stage, the highest total recorded by any player at a World Cup group stage since Miralem Pjanić also created 13 for Bosnia and Herzegovina in 2014.

Even more impressively, all 13 of Trossard’s chances have come from open play. That is the highest figure by any player in a single World Cup group stage since Belgium’s own Enzo Scifo created 15 during the 1994 tournament.

Romelu Lukaku also returned to the scoresheet against New Zealand before providing an assist for Alexis Saelemaekers. His World Cup record continues to grow. Lukaku has now scored six goals and provided two assists at the finals, giving him eight direct goal involvements. Both his six goals and eight goal contributions are Belgium records at the FIFA World Cup.

Whether Garcia starts Lukaku again remains uncertain, but another goal would see the striker score in consecutive World Cup matches for the second time, having previously achieved the feat against Panama and Tunisia during Belgium’s run to the semi-finals in 2018.

This will be the first-ever meeting between Belgium and Senegal.

The historical trends offer mixed encouragement for the African side. Senegal have lost each of their last four World Cup matches against European opposition, all coming across the last two tournaments against the Netherlands and England in 2022, followed by France and Norway in 2026. Before that run, however, they had lost only one of their first five World Cup meetings with European nations, winning three and drawing one.

Belgium, meanwhile, have generally enjoyed facing African opposition at the World Cup. They have lost just one of six such meetings, winning three and drawing two. That lone defeat came against Morocco during the group stage in 2022, although none of those encounters came in the knockout rounds.

The Opta supercomputer believes Belgium hold the advantage heading into Wednesday’s contest. The Red Devils won 45.6% of the 25,000 simulations inside 90 minutes, compared to Senegal’s 27.0%, while 27.4% finished level after regulation time.

Overall, Belgium have a 59.0% probability of reaching the Round of 16, with Senegal given a 41.0% chance of progressing.

The numbers suggest Belgium should edge the contest, but Senegal’s explosive attacking display against Iraq has shown exactly what they are capable of. If Sarr maintains his outstanding form and the Lions of Teranga can tighten up defensively, this promises to be one of the most competitive ties of the Round of 32.
