Chelsea have made a move in a determined attempt to sign Napoli’s £40m-rated defender Kalidou Koulibaly.
Blues boss Antonio Conte has made Koulibaly his No.1 defensive target and they are now ready to firm up their interest with a mega bid.
Napoli are desperate to keep hold of the Senegal centre half who was also a target for Everton.
The Serie A giants scared off Everton by demanding £45million but Chelsea are still on the case – and are ready to test Napoli’s resolve with a mega bid.
Chelsea are still in the market with a centre half their No.1 priority to back up John Terry and Gary Cahill with Kurt Zouma coming back from injury.
Conte wants to strengthen his defence with pace, power and a younger option and Koulibaly fits the bill.
Napoli are trying to offer Koulibaly a new deal and insist they will not sell.
But that has not put off Chelsea who are determined to get their man before the window shuts in a fortnight.
