Belgium and Manchester City winger Jeremy Doku has revealed the frightening health ordeal he endured during the 2026 FIFA World Cup, describing it as one of the most challenging moments of his football career.

The 24-year-old disclosed that he developed serious medical complications while representing Belgium, forcing him to seek urgent treatment and ultimately withdraw from the national team’s camp.

Doku explained that the problems began after one of Belgium’s World Cup matches when a persistent cough refused to subside despite receiving medical attention.

As the days progressed, his condition deteriorated significantly. He began experiencing severe chest pain that affected his breathing and movement, making it increasingly difficult to participate in training sessions.

The winger admitted that even routine physical activity became exhausting as his health continued to decline.

The situation became even more alarming when he started coughing blood, prompting further medical examinations. Doctors later discovered fluid in his lungs, a condition that required immediate attention.

The diagnosis explained why he had been struggling physically throughout the tournament and confirmed that he was not fit enough to continue competing.

After discussing his condition with Belgium’s coaching staff, Doku accepted that remaining with the squad was no longer possible.

Around the same time, he received unexpected news from home that his wife had gone into labour earlier than expected.

With his health compromised and unable to contribute on the pitch, he made the decision to leave the World Cup camp and return to be with his family.

The trip home turned into an unforgettable moment as Doku welcomed his first child, a son named Praise. He described the experience as deeply emotional and said becoming a father provided comfort during an otherwise difficult period.

Preparing for the birth, he sought advice from family members and watched parenting videos to better support his wife.

Now fully recovered, Doku has reflected on the experience as a reminder of how quickly circumstances can change. From battling a serious illness during football’s biggest tournament to celebrating the arrival of his son, the Belgian international says the events transformed both his personal life and perspective on the game.
