It's safe to assume the pressure of Portugal's disappointing Euro 2016 campaign is getting to Cristiano Ronaldo after the Real Madrid star lobbed a reporter's microphone into a lake.

The frustrated player was walking with his teammates from the team hotel when a reporter from Portuguese outlet CMTV approached and, according to The Guardian, asked if he was prepared for Portugal's final group-stage match against Hungary.

Without hesitating, Ronaldo snatched the microphone away from the reporter's hand before launching it into the nearby lake.

The outburst comes after Ronaldo missed a penalty during a 1-1 draw with Austria to set up a crucial encounter with group leaders Hungary on Wednesday.

Portugal, which opened the tournament with a draw against Iceland, sits in third position in Group F with two points.
