Everton are set to make an offer for Kalidou Koulibaly according to reports.
Gazzetta dello Sport suggests that the Toffees will soon submit a bid for the French centre-back who is widely expected to leave Naples this summer.
Roberto Martinez is on the lookout for a new central defender after losing Sylvain Distin and Antolin Alcaraz and Koulibaly is among the names being linked with a potential move to Goodison Park.
