During the summer transfer window last year, Chelsea supposedly had identified Napoli centre back Kalidou Koulibaly as the primary target to reinforce the defence. However, Napoli chairman Aurelio De Laurentiis did what he could to make a potential switch practically impossible, first by setting ridiculous and ever-increasing transfer fee demands and then managing to convince the defender to sign an extension with the Partenopei last September.
(Ed. note: Chelsea instead moved for David Luiz, and that decision has worked out quite well, to say the least.)
While Koulibaly ultimately decided to stay at Napoli, the club have so far failed to meet his ambitions. Out of the Champions League in the round of 16 following two 3-1 defeats to Real Madrid and standing ten points behind Juventus in the Serie A, Koulibaly's agent Bruno Satin is already casting doubts on whether his client will stay at the San Paolo Stadium next season.
"At the moment, we don’t want to talk about [Koulibaly's] future but with a president like this who has a lot to say, it is difficult for us to affirm 100 per cent that he will be staying at Napoli next season. [But] he wants to finish the season on a high even if it will be almost impossible to surpass Juventus for the league title."

This season Koulibaly has remained a central piece of Napoli's line-up and no doubt remains a quality player who could possibly suit our plans for the future. But at a rumored €70 million transfer fee, Chelsea would be fools to go after him at this time.
