Everton will submit a £33million bid for defender Kalidou Koulibaly on Friday, according to a report.

Italian publication Gazzetta dello Sport claim the Merseysiders will meet with Napoli to hold talks about the transfer of the Senegal centre-back.

It is said the Serie A club’s sporting director Cristiano Giuntoli will meet with Everton officials in Milan and the Merseysiders will offer £33million for Koulibaly.

However, it is not expected that Napoli will accept the bid as they hold out for a fee closer to their £50million valuation.

Manager Ronald Koeman is in the market for a new centre-back as Manchester City prepare a record-breaking bid for John Stones.

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

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

As reported by Football Insider, Everton have held extensive talks to sign Witsel in a £30million deal from Zenit St Petersburg but talks have collapse.

Everton are said to be backing Koeman with a £100million transfer kitty and the Everton boss is said to believe it is necessary to make significant changes to a squad that underachieved last season.

However, the most important deal could be retaining striker Romelu Lukaku who is wanted by European heavyweights Chelsea and Bayern Munich.
