Manchester United are "always in the running" for Napoli centre-back Kalidou Koulibaly, according to Italian journalist Niccolo Ceccarini.
Ceccarini has claimed that despite interest from elsewhere, Ole Gunnar Solskjaer's side will be in the argument for the Senegal international if he seeks pastures new in the upcoming window.
"Koulibaly has been clear for some time," Ceccarini told Tuttomercatoweb. "Napoli evaluates him at €100m (£90m) but today it is very difficult to bring home such a figure.
"For him, a future in the Premier League is possible. Manchester United is always in the running, but Liverpool and Tottenham have also recently joined."
The centre-back has made 233 appearances for his Italian club since arriving from Genk in 2014.
