What happens when you take three Ireland international players - Richard Dunne, David Forde and Conor Sammon - and quiz them on their football knowledge?
This rather clever little promo video from team sponsor Three does just that.
Question one: "Thierry Henry is a…?"
Some of those were actually a bit tough. Also: "Would you say you're the Sammon of knowledge, Conor?" "I am, yeah." Confident man.
Matthew Nolan (9) and Matthew Hanley (8) from St Oliver Plunkett School, Malahide, did a grand job as quizmasters.
Best of luck to the boys in green later in the World Cup Qualifier.
