​The Belgium injury crisis has emerged as the defining storyline ahead of Friday’s World Cup quarterfinal against Spain, forcing the Red Devils to rethink their plans just as the tournament reaches its most pivotal phase. Belgium arrive in Los Angeles riding an 18-match unbeaten streak and buoyed by the most emphatic victory of any team left in the bracket, yet head coach Rudi Garcia must now navigate two selection dilemmas that were never part of the plan.
The most serious blow in the Belgium injury saga is Amadou Onana’s torn ACL, sustained during Belgium’s 4-1 victory over the United States in the Round of 16. Onana has been the team’s primary midfield enforcer throughout the finals, and losing him for the remainder of the tournament represents a major setback for a Belgium side that relies on his ball-winning prowess and protective shield in front of the defense. With Onana sidelined, Garcia is expected to move Youri Tielemans into a deeper role alongside Hans Vanaken to help shield the back line, a reshuffle that could also release Kevin De Bruyne to operate with greater freedom higher up the pitch after he was rested entirely against the United States. Nicolas Raskin is also in contention to feature in this revamped midfield, offering Garcia some cover, though it does not fully compensate for what Onana brought in terms of defensive coverage. Belgium’s ability to disrupt Spain’s possession-dominant midfield, anchored by Rodri, Pedri, and Dani Olmo, will be put to the test without their premier screen for the first time in the tournament.
The second issue fueling the Belgium injury crisis concerns defender Zeno Debast, who has yet to play at these finals due to a leg injury and faces a late fitness test ahead of kickoff. Debast was once Belgium’s preferred option at the back, but his absence through the knockout rounds has left Garcia relying on a back line featuring Timothy Castagne, Brandon Mechele or Koni De Winter, and Maxim De Cuyper. If Debast does not pass fit in time, that same group is expected to line up again against Spain, meaning Belgium’s defense could be unchanged for a must-win match against the only team in the tournament not to have conceded a goal.
Despite these troubling setbacks, Belgium still possesses quality across the pitch. Charles De Ketelaere found the net twice in the win over the United States and continues in the false nine role, while De Bruyne’s return to the starting lineup after his rest provides Belgium with a proven creative outlet regardless of how the midfield is configured. Yet facing a Spain side built on suffocating possession control makes the timing of the injury crisis particularly unfortunate—Onana’s loss removes the very type of ball-winner who would ordinarily be tasked with breaking up Rodri and Co. Belgium’s progress in this knockout phase hinges on how effectively they adapt to these personnel changes and whether they can blunt Spain’s rhythm enough to vie for a spot in the semifinals.
In the bigger picture, the injury issues arrive just as Belgium’s depth is tested at a crucial moment. Garcia will need to balance risk and reward—preserving structure and defensive solidity while unleashing De Bruyne and the rest of a capable attacking corps—if they are to overturn a Spain side whose approach has repeatedly overwhelmed opponents. The match promises to be a tactical clash of two contrasting philosophies, with Belgium hoping to frustrate Spain and seize opportunities on the break or set pieces. The outcome may well come down to whether the Red Devils can compensate for Onana’s absence in central midfield and whether Debast, if fit, can contribute meaningfully to a defense that has to withstand one of the most precise, possession-heavy attacks in the tournament. In short, Belgium’s path to the last four will depend on how well their reshuffled lineup can hold firm, disrupt, and create at the other end without their two key regulars.
