Napoli made enquiry after Al-Nassr striker Duran

The Colombia international only left Aston Villa for the Saudis in January for a fee rising to €88m.

But Turkish media sources state Al-Nassr and Duran's agents are now exploring the prospect of a quick return to Europe this summer.

Napoli have already been linked, though it's suggested Al-Nassr's asking price is proving too steep.

Given the fee paid just six months ago, Al-Nassr are reluctant to sell at too great of a loss.
