Napoli president Aurelio de Laurentiis says their transfer plans are not over.
The Azzurri swooped for Inter Milan attacker Goran Pandev last week.
De Laurentiis said: "Pandev is a great player. Walter Mazzarri, who is a genius, considers Pandev a player who can take on many different attacking roles.
"We are still looking on the market, as we are a growing club and look at every detail. There could be another announcement within days, or we can talk about it again in January."
