Chelsea captain John Terry is showing all the qualities of a future manager, the club's interim boss Guus Hiddink said on Friday. Terry, 35, is keen to continue his playing career at Stamford Bridge but has not yet been offered a new contract for next season. Hiddink said decision was not down to him, but in the longer term he could see the former England central defender as a manager. "In some players you see while they are playing there might be managers inside them already," the Dutchman told a news conference. "You see that most of the time in midfield positions or centre-backs. These guys are already leaders. "In my career I've had some examples like (Southampton's) Ronald Koeman in my first spell at Eindhoven, who you could see was tactically very strong and a leader. "And (Watford's) Quique Sanchez Flores at Valencia too." Terry would need "extra courses" and would be well advised to start as an assistant, Hiddink added.
