Head Coach Colin O'Brien has seen goalkeeper Gavin Bazunu and forward Festy Ebosele promoted to the Under-21 and Under-19 squads respectively, while he has called in Manchester United duo Charlie McCann and Ademipo Odubeko for the first time.
The Ireland squad will stay at CityWest Hotel, Dublin because that will be the base for all teams competing in this summer's finals tournament - which runs from May 3-19 - and they will travel to Waterford and Tallaght Stadium for these friendly games, just like they will for tournament games in the summer.
Under-17 Head Coach Colin O'Brien is looking forward to getting the players into camp for what will be the final time before tournament preparations begin next month.
"It's another opportunity for us to do some preparation with the players. All the players are looking forward to coming into camp.
"All the work we have done this year has been to mirror the tournament scenarios. We're looking to acclimatise the players as best as possible."
Waterford FC and Shamrock Rovers Season Ticket holders get free access to the respective games and O'Brien hopes to see both fanbases back the team against Finland.
"The fans will see a group of players that will give all for their country. These matches will be the first competitive games the players will have played on home-soil, in May. The fans in Waterford and Dublin will be the chance to see that"
This will be the third straight year that O'Brien will lead an Under-17s squad to the finals tournament following experiences in Croatia (2017) and England (2018), where they reached the quarter-finals on both occasions.
