Manchester United and Arsenal are reportedly interested in signing Napoli and Senegalese defender, Kalidou Koulibaly.
The Senegalese defender joined the Partenopei from Gent in the 2014 season.
His performance since then has been highly impressive and has yielded the results of having his name ticked in the prospect of being signed by a big club.
United and Arsenal are not the only club interested in the 24-year-old, the likes of Barcelona are closely monitoring his developments.
According to II Mattino, Barcelona have a long-standing interest in the Senegal international, but Man United and Arsenal are preparing to go head-to-head for his signature at the end of the season.
Centre-back Koulibaly came through the youth system at French club Metz.
