Serbian defender Nikola Maksimovic is set to leave Napoli at the end of this season.
According to Nicolo Schira, several European clubs are interested in the player, with West Ham United and Everton already in contact with his agent Fali Ramadani.
The two Premier League clubs have requested information from Ramadani and may follow up their interest with bids this summer.

Maksimovic has fallen down the pecking order at Napoli, starting just 11 league games this season.
Roma and Inter Milan are also keen on the player, and Maksimovic may see remaining in Serie A as a better option.
However, the 29-year-old needs to play regularly at this stage of his career, and a move to West Ham could be ideal as the club needs more depth in defence.
The defender will be available on a free transfer, and his signing could prove to be a bargain for the Hammers.
He has the quality and the experience to play in the Premier League and is at the peak of his career right now.
Everton also need to strengthen their centre-back options. The likes of Yerry Mina have been unreliable in terms of fitness, and Maksimovic would be a handy option for Carlo Ancelotti.
The Everton manager worked with Maksimovic during his time at Napoli and will know all about his qualities.
