Chelsea interested in Napoli's Koulibaly: contact with agent in London

Chelsea continue to think about bringing a defender for next season and continue to look at Serie A for reinforcements. After the Skriniar and De Ligt ideas, the Blues are also looking at Kalidou Koulibaly. In the last few hours, there was contact with his agent in London. The high prices for De Lige and Skriniar have forced Chelsea to enquire for information about Koulibaly, as his price will be lower due to the fact the Napoli player has one year left on his contract.
