John Gregory has been appointed as the new head coach at Indian Super League side Chennaiyin.
The former Aston Villa, Derby and QPR boss replaces Marco Materazzi as manager of Chennaiyin, who are based in Chennai in south east India.
Gregory most recently managed Crawley but stepped down from his position in 2014 to undergo heart surgery.
The 63-year-old praised the work done by ex-Italy defender Materazzi in charge at Chennaiyin and said he was grateful for the opportunity given to him by the owners.
