Kurt Zouma had originally been expected to be out for six months. Chelsea defender Kurt Zouma has stepped up his recovery from a serious knee injury and could be fit for the start of next season. Zouma, 21, was expected to be sidelined for six months after rupturing the anterior cruciate ligament in his right knee in February, ruling him out of the rest of Chelsea's season and France's Euro 2016 campaign. But just three months later, he has posted Instagram footage showing him running again as he continues his rehabilitation at the club's Cobham training complex.
