The Spaniard is positive that the Partenopei will complete moves for their key targets and also spoke about his confidence in beating Lazio in the Coppa Italia on Wednesday.
"I have spoken with the president and I am convinced that we'll make some moves," Benitez told Radio Kiss Kiss. "We're working on a few things. [Riccardo] Bigon is taking care of all that. There are about 2,000 names being mentioned in the newspapers, but I know who we're after.
"I'll be happy when the window closes on Friday, but I'll be even happier if we beat Lazio tomorrow. The Coppa Italia is a goal of ours, and a win tomorrow would see us go a step closer to that goal.
"At the moment we're close to the big teams at the top of the table. We're all very positive about the future, because these lads are all the right age, with plenty of room for growth."
Napoli are currently third in the Serie A table.
