Since the 39-year old Snape has helped South Africa emerge as No 1 Test side, he was preferred over others for monitoring the team's performance.
Former India pacer and the head of GMR Sports Pvt. Ltd, T A Sekar said "We're happy to welcome Jeremy as Performance Coach."
"We believe he has the right credentials to help Delhi Daredevils achieve its goals. We are sure he will bring in fresh ideas and help the coaching staff bring the best out of the players in a high performance environment.
"We are sure that Snape will enable the players be on the edge of their comfort zones as they deliver high performance through the coming season," he added.
Since Delhi Daredevils have been struggling to reach the last leg of the cash-rich league despite a good team and a good track record during the start of the tournament, the presence of a performance coach would help the team track their weaknesses and work towards it.
"We want to leave no stone unturned and help the team in its quest to be competitive through the IPL season. We are sure that Snape will enable the players be on the edge of their comfort zones."
Pleased with the new association, Jeremy Snape, the founder of Britain's leading performance coaching companies, said that "The mental side of T20 is both fascinating and vital and I look forward to supporting the players and coaches to achieve their ambitions," he said.
