Ranieri said: "I needed Iaquinta as he is a player who attacks space and, knowing we would be under pressure, needed two fast wingers. That is all there is to it."
The Juve boss also left out Tiago, who is being linked with a return to Portugal in January.
"Sergio Almiron is a splendid player and when we put together the squad we tried to form a real team. Almiron can play or not and the same goes for Tiago. I pick players thinking of who can help us win, not who cost more on the transfer market."
