It appears organisers have overcompensated, with too much chlorine in the water leaving the Team USA water polo captain baffled.

“I could barely open my eyes for the final quarter,” said Tony Azevedo, after their victory over France on Wednesday.

“This is the Olympic Games and they are putting so much chlorine in the water that people can’t see. You can’t have that.”

Rio officials insisted there was “absolutely no risk”, nor any ill effects, despite complaints from both USA and France.

The diving and water polo pools should be clear from Thursday.
