Ronaldo is yet to score for Portugal who are winless in Euro 2016. The Real Madrid star missed a last minute penalty in the 0-0 draw against Austria.
Ahead of their final group game against Hungary, Ronaldo grabbed the microphone of a reporter who approached him for an interview and threw it in a nearby lake.
The journalist approached and asked Ronaldo, in Portuguese: "Are you ready for the game today?"
Ronaldo was irked by the question and he grabbed the microphone from the reporter and threw it into the lake and continued the walk with his teammates.
