Soccer fans were surprised when Cristiano Ronaldo snubbed Coca-Cola during his press conference on Monday.

The superstar, who plays for Portugal, removed two bottles of Coca-Cola from the table then declared everyone should water.

His rant caused shares of Coca-Cola stocks to plunge $4 billion in value on Tuesday.

Last year, the champion soccer star revealed his disapproval of his 10-year-old son, Cristiano Ronaldo Jr., consuming the sugary soft drink and eating potato chips.

“We’ll see if my son will become a great footballer. Sometimes he drinks coke and eats crisps and it irritates me, he knows that.”

Ronaldo, 35, has four children, including twins Eva and Mateo and daughter Alana Martina.

Fans were surprised because Ronaldo has promoted Coca-Cola and its products over the years.

Twitter users posted old promotional ads that show Ronaldo holding a can of Diet Coke, as well adverts for KFC and McDonald’s in recent years.

But not everyone was critical of Ronaldo’s contradictions.

Boxer Josh Warrington tweeted: “We’ve all contradicted ourselves before haven’t we…?”
