The 28-year-old made his return from an Achilles injury as a substitute during Viola's 1-0 win over Lazio on Sunday.
However, Montella said that he does not want to give Luigi Del Neri's men any advantages before they face off at the Stadio Luigi Ferraris.
"I won't tell you whether he will play or not," Football Italia quotes the 38-year-old as saying.
"I don't want to give them any kind of advantage. We are just all happy that a player of his calibre is at our disposal."
Aquilani has featured twice for his new club since moving from Liverpool in the summer.
