We can all recall the pictures of Robbie Keane and Damien Duff from their underage careers. They were fresh faced, youthful, but above all, successful.
Even now, we can name the players in our current U21 set-up, trying to pick out which players are destined for success.
With that in mind, we've reefed through the Sportsfile archives to dig up old photographs of Ireland internationals. Some of the players in question are retired, some are coming to the end of their careers, some are in their prime and some are only just getting started when it comes to senior football. All of the photographs are of the players playing with Ireland at a variety of underage levels, from U15 to U21.
The common denominator is that all of these players have made at least one senior appearance for the Republic of Ireland
The photos span almost 20 years and there are 15 to get. Unfortunately for you, Robbie Keane isn't one of the answers and Jason Gavin never played senior international football for Ireland.
So without further ado, can you get 15/15?
