The U21 international scene is a bit of an odd one. It features some players you may know, but ones who are not deemed quite ready to feature for the senior side.
It was also one not given much attention for quite a long time. That may have changed in recent times, but it makes this quiz fairly difficult.
We want you to name the most capped Ireland U21 players, with 12 individuals earning 15 or more caps. To help you out, we have given you the years they were active with the U21s.
Some have gone on to be important players in the senior squad, while others never really kicked on. You have seven minutes to name them all.
