Kalidou Koulibaly has been plying his trade in Serie A for nearly six years now.
Koulibaly would join Napoli from Belgian outfit Genk in the summer of 2014.
The Serie A powerhouse are believed to have paid just shy of £7m for the imposing central defender.
Since making the switch to Italy, Koulibaly has gone on to cement himself as one of the top centre-backs in Serie A.
In total, the 28-year-old has featured 232 times for the Naples-based club.
The Senegalese international has made just 14 league appearances this season, but that is largely due to some recent injury troubles.
And whilst Napoli aren’t having the greatest campaign, Koulibaly has still been in good form.
The centre-half has been particularly impressive in the Champions League this season.
Napoli didn’t lose a single group game, and would even pick up a hard-fought 2-0 victory over current Champions League holders Liverpool.

Man United linked with Koulibaly
The former Genk star is currently contracted to Napoli until 2023.
But recently, Koulibaly has been linked with Manchester United.
The Mirror reported at the beginning of this month that the Red Devils would step up their efforts to secure Koulibaly’s services as soon as the summer transfer window opens.
Man United are lacking quality in the centre-back department, with Harry Maguire arguably their only top centre-half.
So, signing Koulibaly would likely prove to be a solid bit of business for the Manchester powerhouse.
Now, the Mirror, citing Italian outlet Il Mattino, are reporting that Man United are in pole position to land Koulibaly.
However, United may face some competition for the Napoli standout, with the report from the Mirror claiming that Arsenal, Chelsea and Tottenham are also said to be interested in Koulibaly.
