Belgium winger Jeremy Doku has disclosed that he coughed blood and suffered severe chest pain during the 2026 FIFA World Cup, forcing him to seek emergency medical treatment before eventually leaving the national team camp for the birth of his first child.

The Manchester City star shared the details in a video posted on his YouTube channel on Saturday, describing the period as one of the most difficult experiences of his career.

Doku explained that the health problems began after Belgium’s match against Tunisia when he developed a persistent cough despite recovering from an earlier illness.

“I started coughing every second. I couldn’t say a word without coughing,” he said.

The 24-year-old added that his condition worsened after attending church with the team, when he suddenly experienced intense pain in his chest.
