SSC Napoli v Bologna FC - Serie A — Koulibaly has been a vital cog in the defence for Napoli

KALIDOU KOULIBALY

The impenetrable Chelsea defence of last season has been a shadow of itself this year around. Shaky at best, the Londoners need to buy someone to solve their woes at the back as they have been leaking goals.

With David Luiz out of favour, Gary Cahill proving to be error prone and Rudiger not yet ready to make the Centre Back position his own, Senegalese international Kalidou Koulibaly looks like he's the one missing piece in the Chelsea squad.

Koulibaly is a strong and a no nonsense kind of defender. He's fast, tall and elegant on the ball. His ability to read the game is among the best in his position. Coming out of the defensive line to clear dangers is one of his biggest strengths.

The right footed defender at the heart of the defence will add much needed reinforcement to the back line of the Blues. His presence,at the back could make it imperious as it was during the days of John Terry and Ricardo Carvalho.
