The highly rated defender has been a target for Manchester United as well. The Old Trafford outfit even submitted a bid for him earlier this year.
According to latest reports,
Chelsea have submitted a 38 million pounds bid for the Senegal
defender. Koulibaly is apparently on top of Chelsea’s transfer wishlist
right now and the player’s agent has fuelled further speculations by
claiming that his client has decided to complete a transfer away from
Napoli this summer.
