Republic of Ireland captain Robbie Keane will not play for his country in next month’s friendly with Greece after he was left out of the squad.
Trapattoni, who has selected Norwich City’s Wes Hoolahan, is looking forward to taking on the Greek side at Dublin’s Aviva Stadium on November 14 as he tries to get Ireland’s qualifying back on track after a recent 6-1 loss to Germany.
"I have decided to choose a provisional 26-man squad for this game due to injury doubts over players,” he said.
"As we have a break from competitive games for a few months, I am using this fixture as an opportunity to try out new players and view their potential.
"Greece are currently 10th in FIFA's world rankings, and will provide a very difficult opposition for us.
"Players like (Georgios) Samaras, (Fanis) Gekas, and (Giorgos) Karagounis are extremely talented. I am looking forward to setting our squad up for this challenge."
