With a deadpan face and the slightest tinge of derision, star footballer Cristiano Ronaldo picks up two glass bottles of Coca-Cola, mutters the company's name and sets them aside before holding up a bottle of water. Not long after, the Euro 2020 sponsor saw its market value drop by $4 billion.

The captain of the Portugal football team is a well-known fitness enthusiast. At a press conference in Budapest before Portugal went up against Hungary at Euro 2020, Ronaldo made it well known what he feels about carbonated drinks.

Within seconds of sitting down, the footballer puts the Coca-Cola bottles away and holds a bottle of water up saying, "Agua" (water) in Portuguese in a gesture appeared to encourage people to drink water instead of aerated drinks.
