Ranieri insists Atalanta must be their total focus.
The most important game is always the next one," Ranieri said on Tuesday. "I always think of the next match to be played.
"The choices I make are based on this - on how the players are, how they've been affected by the previous match and how long it will take to recover.
"Now I'll think hard and between tonight and tomorrow I'll come to a conclusion.
"There will be those who will have to take a breather and who will not be able to do it. We'll see. During training I have a thousand ideas, then between the evening and the morning I decide."
