The former Chelsea boss was appointed advisor to the club’s owner, the Bollywood actor and firm producer John Abram, last week and he took charge as manager a day later following the sacking of Portuguese head coach Joao de Deus.
Based in Guwahati in Assam, NorthEast United are languishing in ninth place in the 10-team SuperLeague after eight games. Grant will take charge for the remaining nine games but need not fear relegation as the league is a US franchise-style closed league.
Grant said: "It’s going to take me a few more days to fully assess the team but I can already say there is a great passion for football here.
“The pitches are great, there is a willingness to learn and huge potential to develop football here.”
