Real Madrid are reportedly preparing to make a big offer for Napoli's Kalidou Koulibaly.
The Spanish giants intend to make a move for the Senegalese defender next summer, according to Calciomercato.
The report claims that Madrid see Koulibaly, 28, as a long-term replacement for 33-year-old Sergio Ramos, whose contract expires in 2021.
Koulibaly is a long-term target of Manchester United and currently possesses a price-tag in the region of £100m, although that would be reduced if Napoli do not achieve Champions League football for next season.
The Italian giants are currently struggling in seventh in Serie A after 14 games.body check tags ::
