Napoli defender Kalidou Koulibaly is very unhappy with the club’s decision to reject an offer worth 30 million euros from Manchester United for his transfer.

The 30-year-old center-back has long been rumored to want to leave Napoli and the Red Devils offered him a way out this summer.

Italian newspaper Gazzetta dello Sport reports that the Premier League giant offered Napoli 30 million euros for the Senegalese. Napoli rejected the offer of the English.

Napoli was informed about United’s offer by the Albanian defender manager, Fali Ramadani, according to the Italian daily.

Koulibaly still has one year left in his contract with Napoli and is considering leaving the club he joined in 2014 from Genk for 7.5 million euros.

He is said to be unhappy that Napoli turned down United’s offer.
