Simpson, who is in Mumbai to coach the Under-14 cricketers at the Cricket Club of India (CCI) Cricket Academy, said that Ganguly and Wright have been instrumental in India's success and the two have complemented each other with some fantastic wins abroad.
"John (Wright) is doing a superb job while Ganguly has led the team in Australia and Pakistan from the front and this has helped India to emerge as a very dangerous team," he added.
When asked about batting maestro Sachin Tendulkar's poor form in the recent series, Simpson said "I don't think there is anything wrong with Sachin's form it is only that he needs to recharge his batteries and I would love to talk to him if he needs tips any time".
"Coming back to John (Wright) I think he has played a significant role in moulding the Indian team and if I were to be connected with the Board of Control for Cricket in India (BCCI) I would have definitely given him an extension," he added.
"Personally I think John (Wright) has got a few more years as a coach and all the hard work he has done with the Indian team has paid off at last. It is always better to have a coach who can deliver the goods than a coach with a big name tag," Simpson said.
Speaking about Team India, Simpson said, "I think the Indian fielding, which was quite good during the Pakistan tour, could improve further to get the best out of the present bowling attack as the old saying "catches win matches" still holds good in both forms of cricket".
When asked about Australia's forthcoming tour of India where they will be playing a four-match Test series, the former Aussie skipper, said, "if you want to beat the Aussies in the forthcoming Test series then the Indians will have to improve in all departments of the game.
"It is not easy to beat the best team in the world if you don't have the right combination and if you don't play really hard," he added.
Speaking about the increasing number of bowlers with 'suspect actions', Simpson said, "I don't want to take names here but I can only say that some people have got away with suspect actions though the International Cricket Council (ICC) can improve the system for the future".
Talking fondly of his young wards, Simpson said, "I find coaching these kids a real pleasure as well as a challenge as you have to get their attention all the time".
"It is very satisfying to see a smile on the youngsters' face when they really understand what is expected of them and that gives me immense satisfaction," he added.
