Kumble, who was with MI since January 2013 has resigned from the post today (November 30), a media release from the IPL team said.
Under the guidance of 45-year-old Kumble, Mumbai won both IPL and Champions League Twenty20 (CLT20) titles. Kumble was with the team when MI won both their IPL titles, in 2013 and 2015. They made it a double in 2013 by pocketing CLT20 trophy.
"I sign off with the obvious satisfaction of moulding a set of brilliant individuals to a high performing unit. Over the three years, MI met unprecedented success, winning the IPL twice and the Champions League once, winning both trophies in the same year (2013) being our crowning glory," Kumble said.
"As I move on to pursue other interests around cricket, I shall be amiss if I do not express my deep sense of appreciation to the Ambani family, particularly Smt Nita Ambani, Akash Ambani and Nikhil Meswani, for their unstinted support and empowerment.
"The players and my support team (coaching and non- coaching staff) have been an admirable bunch and were a joy to work with. Finally, I thank the MI fans for their constant support. I bid the Mumbai Indians farewell, convinced that I remain a member of the Ambani family," he added.
"Mumbai Indians is grateful to Anil Kumble, India's highest wicket taker in both Tests and one days for his contribution in strengthening the Mumbai Indians Franchisee. In his first year as the Mentor, Mumbai Indians won the IPL and the Champions League in 2013. Mumbai Indians won the IPL once again in 2015," the team said in a media release.
Akash Ambani said, "Shri Anil Kumble is a legend and we thank him for all that he has done for Mumbai Indians. I have personally learnt a great deal from him and will continue to seek his wise counsel and guidance. We take this opportunity to wish Shri Anil Kumble all the very best in all our endeavours."
