Cristiano Ronaldo appeared to cut an irritated figure while the Portugal players were out walking near their team hotel in Lyon, France.
Having already been christened Euro 2016's most frustrated man after attempting 23 shots without scoring a single goal, Ronaldo was pressed by a reporter from CMTV, who asked the superstar if he was prepared for Portugal's final group game against Hungary.
Ronaldo reacted by snatching the reporter's microphone from his hand and throwing it into a lake.
The 31-year-old Real Madrid forward has been under pressure at Euro 2016. He refused to shake hands with Iceland's players after Portugal's 1-1 draw in their opening game, and he missed a penalty in their second group match -- a 0-0 draw with Austria.
Jose Delgado, a correspondent for Portuguese daily A Bola, told Reuters that Ronaldo was frustrated by his poor performances.
"The hours before the game are always difficult for the players, and I don't think it's a good idea they mix with journalists because things like this may happen," he said.
"Ronaldo has been anxious in the last few days because he didn't play well in the opening two games. Let's see what he can do against Hungary and if he can come to his usual level."
