Instead of the Italian's favoured 4-4-2 formation, Trap has opted for 4-5-1 with Shane Long as the lone frontman and Wes Hoolahan playing in a deeper role behind the target man.
At the back, Keiren Westwood starts in place of the injured David Forde in goal, and he will play behind a back four of Seamus Coleman, Ciaran Clarke, John O'Shea and Marc Wilson.
QPR's Richard Dunne has not been included in the squad as he attempts to regain full fitness.
Trapattoni looks set to continue with playing Jonathan Walters out on the wing, with James McCarthy and Glenn Whelan in the centre, and Robbie Brady getting the nod ahead of James McClean.
