“Mario Yepes had a muscular problem on Friday and his presence is in doubt,” explained Coach Colantuono.
“Stefano Lucchini is also out, but we won’t weep about it. I am thinking about various different solutions, as I could use three at the back or even four.
“I’ll decide at the last minute, knowing I can also count on Giulio Migliaccio, who has done well as a centre-back in the past.”
Atalanta are fresh from holding Inter to a 1-1 draw, while Livorno have one point from five games.
“If we think this is a walk in the park, then we may as well stay at home,” warned the tactician.
“The Amaranto are a good side set out to secure safety and play with great dignity. The point with Inter gave us enthusiasm, but it’s up to us now to keep the right approach. We also need to be more efficient in front of goal.”
Atalanta squad for Livorno: Baselli, Brivio, Caldara, Canini, Carmona, Cazzola, Cigarini, Consigli, De Luca, Del Grosso, Denis, Gagliardini, Kone, Livaja, Marilungo, Migliaccio, Moralez, Nica, Polito, Raimondi, Scaloni, Sportiello, Yepes
