West Ham and Toulouse were continuing talks on Saturday over Issa Diop.
The Daily Mail says the Hammers are continuing discussions with Toulouse over a £22million deal for Diop.
Sevilla have also made an offer for the 21-year-old centre back though less than West Ham.
A fee is still to be agreed while the France Under 21 international is also looking for greater personal terms than have been proposed.
Everton are also interested in Diop.
