Ki Sung-yueng is searching for the right word. 'I threw the weapon,' he starts. 'What's it called? The one with the pin?' A grenade? 'Yes, a grenade.'
With that, he motions with his teeth to pull the pin before bowling overarm towards the corner of the room. 'Then, you run and... this, you do this,' he says, raising both arms in protection of his head.
The point Ki is trying to make is this: he is ready for war. Not some cliched battle at the bottom of the Premier League with Newcastle United, but real war with grenades and guns.
