Former England boss Fabio Capello has explained why Kalidou Koulibaly is struggling in the Premier League. The 31-year-old joined Chelsea from Napoli in a deal which cost £33million and, initially, it looked like a great piece of business after scoring a superb volley on his competitive debut.
However, Koulibaly has become subject to growing criticism following his return from suspension after picking up a red-card in a 3-0 loss to Leeds United. He the proceeded to play a role in the Blues' defeat against Southampton a little over a week later.
And Capello believes that the Senegal international just needs to adapt to the speed of the Premier League after spending eight years in the Serie A. Koulibaly featured 236 times for Napoli in the Italian top-flight, establishing himself as one of the league's leading defenders.
