Napoli fullback Faouzi Ghoulam has stalled new contract talks.
With his deal to expire in June, the defender has been linked with Chelsea and Manchester City this week.
Gazzetta dello Sport says the stumbling block is Ghoulam's insistence on a buyout clause being inserted in the new deal. Napoli are prepared to agree to an option, but the stumbling block is the price.
The left-back wants a fee of €25m set, while Napoli are demanding €35m.
