Napoli are focusing on their midfield by closing in on both Gokhan Inler and Tottenham's Wilson Palacios.
The Partenopei are strengthening their squad after qualifying for the Champions League group phase.
A fee has been in place with Udinese for Inler for a month now, but the player is struggling to agree personal terms with Napoli.
According to the Gazzetta dello Sport, a decisive meeting is due next week, as Inler returns from international duty with Switzerland on Monday.
Udinese want the situation resolved before they begin pre-season training on July 10.
Meanwhile, Napoli are also stepping up their bid for Tottenham midfielder Palacios.
The 26-year-old was at first seen as an alternative to Inler, but is increasingly likely to arrive regardless of the other negotiations.
