Chadha was confident of his chances going into this event, coming in on the back of two PGTI tour wins.
"This is a short course and one has to keep the ball in play. A player has to come in with a game plan and stick to it. I have always enjoyed playing on this course, having top-10 finishes in the last three editions and I hope to go all the way this time," said the 24-year-old, known for his long drives.
Maharashtra's Mane was also hopeful of doing well in this first professional season, having won two PGTI titles in the last four weeks.
"I definitely would like to carry my good form into this tournament. As its still early days for me as a pro, all my goals are short term and I like to take things on day at time. This is one of the most lucrative and prestigious tournaments on the calendar and the field is very tough," said Mane, who was India's No. 1 amateur player in 2014.
