Napoli could agree a new contract with Dries Mertens that has a €35m release clause for Europe and €50m for China.
The 29-year-old Belgian wizard is in the process of negotiating an extension to his current deal, which runs to June 2018.
According to Sky Sport Italia, there is a plan afoot to create the first staggered release clause.
It has become increasingly popular for Italian clubs to create contracts with a release clause set only for sides outside of Serie A.

It has become increasingly popular for Italian clubs to create contracts with a release clause set only for sides outside of Serie A.
This is effectively to avoid a repeat of Juventus poaching star players Gonzalo Higuain and Miralem Pjanic from rivals Napoli and Roma.
However, the Mertens deal could be a brand new version drawn up to avoid Chinese Super League clubs swooping for players.
It’s reported the contract would have a €35m release clause for Europe and a €50m clause if the offer comes from China.
This season he has scored an impressive 15 goals with seven assists in 23 competitive games for Napoli.
