The Italian tactician has said that the forthcoming fixture schedule provides him with the opportunity to experiment with players and systems ahead of crucial competitive games
The Ireland boss named a provisional 28-man squad for the games, with Norwich City winger Anthony Pilkington being the only uncapped player included in the panel.
The Boys in Green face into a packed fixture schedule at the end of May and start of June, which begins with a clash against England at Wembley on May 29.
Trapattoni's team will then host Georgia in a friendly at the Aviva Stadium on June 2 before taking on the Faroe Islands in a World Cup qualifier five days later. They will then travel to New York, where they will play Spain at Yankee Stadium on June 11.
"These matches will provide me with the opportunity to experiment with different players and tactics," Trapattoni told reporters at the squad announcement at Carrick-on-Shannon.
The Italian tactician suggested that the game against England, in particular, represented an important opportunity to play a five-man midfield with one in attack.
"The England game will be important for the new system," he added. "I think we play one and five."
There was no place in the squad for Aston Villa duo Ciaran Clark and Richard Dunne, with the former nursing a foot injury. Dunne, meanwhile, has struggled to regain fitness after battling injuries since June 2012.
Robbie Keane on the other hand has missed LA Galaxy's last three games as a result of an ankle injury, but has nevertheless been included in the provisional panel.
The squad will be narrowed down in the coming weeks pending the status of injuries.
