Out of eight IPL teams, only Kings XI Punjab have an Indian Head coach in Sanjay Bangar.
"It is an Indian Premier League. It is good to have a mix of foreign coaches, foreign players, because you are definitely going to improve your knowledge of the game, but it is not that all foreigners are knowledgeable.
"Please let us not go by that. I think that is something which people need to understand," said the 44-year-old former bowler, who guided Uttar Pradesh to the finals of the Syed Mushtaq Ali All T20 event.
Prasad, who had been associated with the Royal Challengers Bangalore and Chennai Super Kings as bowling coach in the past, is not part of any IPL franchise this year and he termed it as 'disappointing'.

"It is disappointing in a way because it is something that I feel every franchise needs to look at - having Indian coaches as part of their team management - for a simple reason that only four foreign players can play in the 11 and the remaining other seven are Indians," he said.
"It is disappointing to miss out but there is always a learning (process). It is always good to step back and then look at the scenario from outside and then learn a few more things, so that you are better as a coach and better as a person when you start doing this, hopefully from the next year onwards," he said.
"I am going to be part of the media and keep watching games and keep analysing them. I would be able to watch and analyse the games and obviously learn a few things by doing those. So, I hope to increase my knowledge," the former Karnataka player added.
