The 48-year-old Dighe, who played six Tests and 23 One-day Internationals (ODI) for India, will take over the mantle from last season's coach Chandrakant Pandit.
Another former Test cricketer Praveen Amre was also in the running before MCA's Cricket Improvement Committee, headed by chief selector Ajit Agarkar, put the stamp on Dighe's name.
