Chelsea are closing in on the £12 million signing of Saint-Etienne defender Kurt Zouma on a five-year deal, Goal understands.
The 19-year-old revealed earlier this month that he had received a phonecall from Jose Mourinho, and it is believed that conversation persuaded the youngster to pick the Blues over rival suitors Manchester City.
Zouma is regarded as one of the best young central defenders in Europe, though he is currently serving a 10-match suspension for breaking Sochaux midfielder Thomas Guerbert's leg in November.
Since making his professional debut for Saint-Etienne at the age of 16 Zouma has played over 50 games for the Ligue 1 club, while also representing France at youth level.
The deal represents another important step in Mourinho's attempts to remodel the Chelsea squad, following the January signings of Nemanja Matic and Mohamed Salah and sales of Juan Mata and Kevin De Bruyne.
