It is absolutely no secret that in an ideal world, Carlo Ancelotti would have more than three first-team defenders at Everton.

Michael Keane, Yerry Mina and Mason Holgate are the trio at his disposal, and while they have performed rather well since the Italian took over from Marco Silva, we all know the Goodison Park club could do with an upgrade or two in the department.

Of course, with Ancelotti at the helm, that means Serie A is an area where the club could go have a look, and where better than the manager’s former club, Napoli.

According to Gazzetta dello Sport, Everton are one of the clubs ‘remaining vigilant’ on Kalidou Koulbaly and his situation, which hasn’t been optimal this year.

While Aurelio de Laurentiis reportedly refused a €100m offer from Manchester United last year for the Senegalese, his price has somewhat dropped due to poor performances and injuries, with the 28-year-old currently indisposed thanks to thigh issues.

This comes amid after an article revealed the player recently spent €4m on a new flat in Paris, hinting he could be thinking about moving to Paris Saint-Germain, but it’s also worth pointing out Koulibaly was born in France and grew up there for 21 years before moving to Belgium, so him buying a residence in the country of his birth’s capital could mean absolutely nothing.

We’ll have to see, obviously, but with De Laurentiis now open to selling the player, as Gazzetta explain, there will be hope that interested clubs, like Everton or Manchester United, come forward with offers in the summer.

The more the better, as that could lead to a bidding war, and that would reportedly make the Napoli owner ‘happy’.

Everton were strongly linked with Kalidou Koulibaly in 2016, when it was reported in Italy they’d made a €40m offer for the defender.
