Former Everton defender Michael Ball has exclusively told Football FanCast that Kalidou Koulibaly would be a Carlo Ancelotti signing.

The Toffees have struggled defensively this season, with the 29-year-old believed to be close to the top of Ancelotti's wish-list this summer.

Both Mason Holgate and Michael Keane have made costly mistakes in recent weeks, Yerry Mina has been short of consistency, with Ben Godfrey impressing in a fragile Everton backline.

They have the third-worst defensive record in the top-nine in the Premier League this season, which has led to strong reports that they're planning a move for the Napoli and Senegalese captain, who's been one of the most highly rated centre-backs in Europe for several years.

A move to Goodison Park would see the £45m-rated defender reunite with Ancelotti after the pair spent 18 months together during the Italian's spell in charge of the Serie A giants.

But Ball told Football FanCast that a potential move all depends on Ancelotti's budget:

"It’s all priorities of where the finances are, whether we can spend the money.

"Koulibaly has been one that even Jose Mourinho was after at Manchester United, it would be a Carlo signing, not a Marcel Brands type of signing, as there won’t be much resale value and will be the top end of the wage bill at the club."
