Lazio are holding out for a full £35 million from West Ham for Felipe Anderson, as his former club Santos will be due 20% of the transfer fee.
A report by the Daily Mirror claims that the Hammers have seen two bids for the Brazilian rejected.
West Ham reportedly offered an initial £28 million plus add-ons, but Lazio are standing firm in their valuation of the player.
Anderson joined Lazio from Santos back in 2013 and the Brazilian side had a 20% sell-on clause inserted into the deal.
Anderson is expected to leave Lazio this summer and has agreed terms to join the Hammers.
However, the two teams have been locked in negotiations as they aim to meet at an acceptable fee for the player.
Should West Ham complete a deal for Anderson, he could follow Issa Diop through the doors at the London stadium, with the Toulouse defender expected to under a medical on Monday.
