It featured many familiar faces including Robbie Keane, Damien Duff and Andy Reid, all of whom donned Ireland jerseys in the last decade.
But now they and others including Jim McGuinness are studying for the top badge in the coaching game.
As Reid begins his Pro Licence, he joined Kevin Kilbane and Joe Molloy on the Football Show.
"A lot to learn"
"We came in on Monday morning and we've had seminars and course work. A lot to learn," said the former Nottingham Forest and Tottenham midfielder.
"We finish now tomorrow evening and it's been very full on. You don't get very much time to yourself. There's a lot of information to take on, plenty to take on. And the guest speakers have been great."
He explained that compared to the A and B Licences, the UEFA Pro Licence is "geared towards managerial processes".
Where will he be heading next for the club visit requirement? Reid confirmed his desired destination over the next 18 months of his Pro Licence studies.
"I've been wanting to go for a while and I'm going to get it done in the next 2-3 months is Athletic Bilbao," he said.
"I find what they do absolutely amazing. I've been wanting to go for a while. You're talking about a club here that are in the top division in Spain and they do well. But all the kids that come through and all the players that play for them are all from the Basque region.
"I find that amazing. It'd be like Manchester United just using players from the Greater Manchester region. So they must be doing something right to be able to produce these players to go into their first team and to be able to compete in that top league. There must be some sort of structures. I want to go and see what that is. It's a really interesting one for me and I would be doing that club visit as part of my course and I'll be doing reports on it."
