Belgium lost 3-1 to Wales in the Euro 2016 quarter-finals, a result that still puzzles former midfielder Radja Nainggolan. Ashley Williams equalised in the 31st minute after Nainggolan had opened the scoring, and the game was level at half-time. In the second half, Hal Robson-Kanu gave Wales the lead with a memorable turn and finish, before Sam Vokes sealed the victory with a late header. Wales advanced to their first major tournament semi-final, despite being heavy underdogs.
Belgium arrived in France ranked second in the world and boasted a starting XI featuring Eden Hazard, Kevin De Bruyne, Romelu Lukaku and Thibaut Courtois. Yet, their star-studded lineup failed to click against a disciplined and energetic Welsh side. Nainggolan, who scored Belgium's only goal, has since questioned the team's internal dynamics. "I still don't know how we ended up losing that match," he said. "All I can tell you is that, probably, we weren't a particularly tight-knit team." He suggested coach Marc Wilmots treated certain players differently, implying Hazard, De Bruyne and Lukaku were given special status. "Maybe the coach should have developed more cohesion between the players," Nainggolan added.
When Nainggolan says the squad lacked cohesion, he's not just citing poor chemistry — he's pointing to a hierarchy that elevated stars over structure. That imbalance wasn't just a management misstep; it was the reason a well-drilled underdog exposed Belgium's fragility. Talent alone couldn't mask the lack of unity, and in tournament football, that gap is fatal.
