Everton have tabled a £46million bid for Napoli defender Kalidou Koulibaly, according to a report from a reliable journalist.

Sport Italia television expert Ifredo Pedulla claims on his website that the Toffees have made a monumental offer for the centre-back, 25, that would potentially annihilate the club’s transfer record.

Pedulla, who has 151,000 Twitter followers and a massive Facebook following, claims Napoli are keen to retain their player’s services but may have to hand their man a huge salary increase to compete with the wages on offer at Goodison Park.

It is said that Chelsea, Everton’s rivals to land Koulibaly, are not willing to pay more that £37.6million for the defender.

The reported size of bid demonstrates Farhad Moshiri’s growing influence at the club after he became a majority shareholder earlier this year.

Koulibaly would become the most expensive player in Everton’s history if the reported offer was accepted, comfortably surpassing £28million record signing Romelu Lukaku.

Koulibaly has been at Napoli for two years since joining from Metz for £6.5million, and has now played 60 times in Serie A.

The defender played 33 times in the Italian top flight in the 2015-16 season as Napoli finished nine points behind Juventus in second.

Ronald Koeman has been active in his search for players since arriving at Goodison Park this summer, but has been unsuccessful in the hunt for the likes of Graziano Pelle and most recently Axel Witsel.

In other Everton transfer news, target Juan Mata has dismissed speculation surrounding his exit from Old Trafford after telling young fans not to listen to the media.
