"This season he is playing more than I expected, more than he expected and more than everyone expected so he is getting experience levels which are very important." However,

Mourinho insists he currently does not require Zouma to become a leader at the back just yet. He added: "At the moment I see signs of maturity and stability and he does not need to show

leadership because we don’t need and don’t demand that from him. "When one day the team asks him for that then he probably will have that, but at the moment with people like Ivanovic,

Terry, Cech, Cahill, Drogba, Matic and Fabregas, the younger guys don’t need to step up."
