Napoli defender Kalidou Koulibaly's future will be resolved in the next "two to three days" amid strong interest from Chelsea, his agent says.
The Italian boss has made reinforcing his defence a priority and is keen on bringing in a long-term successor to John Terry.
Napoli have remained steadfast in their refusal to sell Koulibaly and have offered the 25-year-old a new contract.
But the Senegal international is reportedly unhappy with the terms of the deal and has publicly declared that he wants to leave Naples this summer.
"Our discussions at the moment are confidential," Koulibaly's agent Bruno Satin told Goal.
"We will be able to announce something in the next few days, two or three days."
Koulibaly made 33 appearances in Serie A for the Partenopei last season. He is contracted to Stadio San Paolo until 2019.
Premier League interest
Goal claims Koulibaly's representatives have offered the player to Arsenal, but the Gunners are yet to make an official bid.
Arsene Wenger reportedly continues to monitor his situation amid a mounting defensive crisis at the Emirates, with Laurent Koscielny, Gabriel and Per Mertesacker all out injured at present.
Everton are flush with cash after selling John Stones to Manchester City for £47.5m ($62m) and are in the market for a central defender to take the place of the England international.
However, Chelsea remain Koulibaly's most likely destination should he opt to leave Napoli.
Conte is reported to have been unhappy with his team's defending in the 4-2 friendly win over Werder Bremen at the weekend and has held a series of transfer meetings upon his return to London from Chelsea's pre-season tour.
The Blues kick-off their Premier League season by hosting West Ham at Stamford Bridge on 15 August.
