Spalletti, who has managed Napoli, Inter Milan and Roma in Serie A, has taken charge of 23 matches as Azzurri head coach and won just 11.
Italy are in Group I of Uefa World Cup qualifying alongside Norway, Moldova, Estonia and Israel.
"I'll be there tomorrow night against Moldova," added Spalletti. "These are the results under my management and I have to take responsibility.
"I love this shirt, this job and the players I've coached. Tomorrow night I'll ask them to demonstrate what I asked even if I haven't been able to get them to express their best."
