Chelsea sign Koulibaly on four-year deal

Kalidou Koulibaly, widely regarded as one of the best centre-backs in world football becomes the second player to join Chelsea this summer.

The defender arrives from Napoli and has signed a four-year deal at Stamford Bridge.

Koulibaly, who is a captain of Senegal widely dubbed a natural leader and a strong character.

Speaking immediately after completing his move, Koulibaly noted that he is fulfilling a dream with his £33.8 million move to Chelsea.

Expectations now believe Chelsea will finally begin to replenish their backline following the departures of Antonio Rudiger and Andreas Christensen.

The deal is Chelsea’s second signing of the summer following the addition of Raheem Sterling earlier in the week.

The former Man City star signed a five-year contract after the Blues agreed to a £45 million deal that could rise to £55 million with the Premier League champions.
