Man Utd, Arsenal in for Koulibaly?

Premier League giants Manchester United and Arsenal could fight it out for the services of Napoli defender Kalidou Koulibaly this summer.

The Senegalese international has been in prime form for the Naples outfit since his move from Genk in 2014, and this has caught the eye of Champions League holders Barcelona.

However, Italian outlet Mattino suggests that Barca may not have an easy route to the 24-year-old, with United and the Gunners prepared to go on a tussle for his signature at the end of the season.

The English duo are believed to be on the search for a new centre-back following their faltering fortunes in the league this season.

Koulibaly has racked 42 appearances in all competitions for Napoli this term.
