Giovanni Trapattoni is weighing up all options over the make-up of his final 23-man squad for Poland and Ukraine, and N o2 Marco Tardelli was at Carrow Road for the Arsenal match last Saturday.
"We follow all players and we decide, Giovanni decides, when will be the right moment," Tardelli said in the Norwich Evening News.
"Maybe it is possible they could play in the friendly, but I cannot say for sure. They know that we follow them, if they play everything is possible."
Tardelli added: "The Norwich team they are good players also Pilkington and Tierney is a good player.
"For us and the international team it is very good because they are young players for the future."
Tardelli has been impressed by Hoolahan's development, the 29-year-old being an integral part of Norwich's double promotion back to the top flight under Paul Lambert.
"I know him (Hoolahan) from two or three years ago when we arrived in Ireland. He is a good player, good quality, a skilful player and I think now more experienced than three years ago," Tardelli added.
"He can play in midfield but he can also play as the second striker. He sometimes plays in this position for Norwich which I think is good."
