Italian giants AS Roma are planning a mega bid for one of Chelsea's best defenders.

The Serie A outfit have already allowed the likes of Mapou Yanga-Mbiwa and Alessio Romagnoli exit the club in recent days, and are now on the search for a new centre-back.

Reports in Italy cites that Roma will look to make a bid of around £25million for Chelsea defender Kurt Zouma, after they failed with a loan offer for Liverpool's Mamadou Sakho.

However, it is highly unlikely that Jose Mourinho will let go of the 20-year-old, given the lack of depth in the defensive setup.

Zouma is currently the only reliable back-up to John Terry and Gary Cahill in the heart of the defence.
