Napoli chief Riccardo Bigon is in the market for a new wide midfielder and Perisic is high on the agenda.
The 25 year-old has scored three goals in 11 games for VfL this season.
Perisic's representative Franco Iovini said earlier this month: "When an important team like Napoli is interested, the player is clearly flattered. There has been some contact with [FIFA agent] Tonci Martic, but nothing more. In August we spoke about it, but to sign Perisic is not easy."
