Now, this one is tough.
Ireland have only made it to six major tournaments in our storied footballing history, spanning a range of 28 years.
In that time, many players have donned the Irish jersey, some with distinction, others not so much.
So, with this in mind, we decided to devise a quiz. Can you name each member of Ireland's major tournament squads?
There are 133 answers, although several players played at multiple championships. Not all managed to get on the pitch, but they all managed to get in the squad. Basically, they got their holidays paid for.
If you fancy yourself as an Irish football egghead, then dive into the quiz below and see if you have what it takes. You have 15 minutes, that should be plenty of time.
