Transfer news and rumours LIVE: Real Madrid monitoring Sterling

Barcelona have added a host of new names to their centre-back watchlist alongside Ajax’s Matthijs de Ligt, Mundo Deportivo reports.

A close eye is being kept on Inter’s Milan Skriniar, 23, RB Leipzig’s Dayot Upamecano, 19, and Napoli centre-back Kalidou Koulibaly, 27. Koulibaly is said to be valued at €130 million ($150m/£113m).

Closer to home, Athletic Bilbao stopper Unai Nunez, 21, is also said to have drawn interest from the Blaugrana, especially with coach Eduardo Berizzo using the youngster so sparingly this season.
