Coca-Cola saw $4 billion dollars wiped off its market value after Cristiano Ronaldo encouraged people to drink water instead of the sugary drink.
The Portugal star removed two bottles strategically placed in front of him at a pre-match press conference and replaced them with a bottle of water.
Coca-Cola’s share price promptly dropped from $56.10 (£39.80) to $55.22 (£39.19).
At one point 1.6 per cent of the company’s value had been wiped off – meaning the market value of Coca-Cola went from $242bn to $238bn – a drop of $4bn (£2.84bn).
A spokesperson added: “Players are offered water, alongside Coca-Cola and Coca-Cola Zero Sugar, on arrival at our press conferences.”
Ronaldo, 36, has a famously strict diet and avoids sugary foods.
