It's about Portugal's Ronaldo, who almost scored the opening goal against Uruguay.
He said, 'It's my header' and even did a goal ceremony.
On the 29th of last month, in the match between Portugal and Uruguay, in the 9th minute of the second half, Ronaldo tried to put his head on Fernand's cross.
Ronaldo even showed a ceremony when the ball passed through the goal.
However, the ball did not appear to have landed on Ronaldo's head, and Fifa corrected the goal for Fernands' goal.
After the match, Ronaldo complained that the ball had hit his head, but it was not accepted.
As the controversy continued, Adidas, the manufacturer of the Qatar World Cup official ball, made a statement.
A sensor is installed inside the official ball, so it tracks the touches of the players and transmits the information immediately to the VAR referee.
Some have argued that Ronaldo must have known it wasn't his own goal, as he hadn't celebrated his signature downpour.
