Chelsea boss Antonio Conte reportedly has Kalidou Koulibaly as his number one summer transfer target.

TMW is of the belief that the Blues boss is determined to strengthen his defence at season's end and Napoli star Koulibaly is at the top of his list.

Conte wanted the French-born Senegal international in the summer but was unsuccessful in his pursuit.

However, it is understood that the Italian plans to add a quality central defender in the next transfer window and is expected to go after the 25-year-old once again.

Napoli president Aurelio De Laurentiis would reportedly consider any bids of around £47.8million (55m euros) for the former Genk and Metz man.
