“My name is Hafthor Bjornsson, from Iceland. I am The Mountain from Game of Thrones. I have a message for Cristiano Ronaldo,” begins the menacing video from the World's Strongest man competitor and actor who plays 'Mountain' in Game of Thrones to the Real Madrid striker.

The video is filmed in a gym with the Icelandic giant lifting impossible quantities of dumbells and grunting ominously.

The scene in Game of Thrones comes to mind while the man-mountain pumps weights and fills up more space than two ordinary people: he faces Prince Oberyn (nicknamed the Red Viper) in trial-by combat, who steps in as champion for Tyrion Lannister.

Despite being poisoned by the Red Viper, Mountain has enough strength to crush his opponent's skull using his bare hands, winning the duel.

Cristiano may consider adding to his Portuguese assists tally after seeing this video;

“I know you’re playing against Iceland in the first game. If you dare to score a goal against my team-mates, I will find you and crush your head like I did to the Red Viper”, continues Bjornsson.

Will Cristiano cave in, or have his head caved in? Unlikely, as the end of the video attests.
