With Napoli set to miss out on Champions League football for next season, it looks likely that this will finally be the season Aurelio de Laurentiis cashes in on one of his most prized assets.
Koulibaly is not short on suitors, with the likes of Manchester United, Chelsea, Liverpool and Paris Saint Germain all ready to go head-to-head for his services.
Leboeuf, who won the 1998 FIFA World Cup with France, has however opined that a move to Old Trafford should be completely ruled out by the Senegalese, as Ole Gunnar Solskjaer’s side have lost the penchant for winning trophies.
'I will never ask him to go to Manchester United for many reasons,' the ex-Chelsea defender told ESPN FC.
'I want him to win some stuff and I think Manchester United is not the club that they used to be and they're not ready to win stuff.
'I think Liverpool would be a good fit with [Virgil] van Dijk, that would be fantastic. Paris Saint-Germain as well with Marquinhos, there would be two great central defenders.
'I think Chelsea will need a player like that. I don't know if Koulibaly will be interested, but even if they have two very good central defenders, Koulibaly I think belongs to another level and would fit very well.
'I know he has a link with Liverpool, Van Dijk and Koulibaly at the back - my God, that's going to be another Red season I guess.
'You have to make a choice at certain points. The question was: "What is the best fit for Koulibaly?".
'Definitely with Van Dijk, and when you're a defender like Koulibaly, that would be the best central defence in the world.'
