The 47-year-old has signed a short-term deal and will link up with the Bangladesh squad before their home two-test series against Australia, which starts on August 27 in Mirpur.

Australian Stuart MacGill was also in the frame for the job but talks between him and the BCB reportedly broke down, leading to Joshi's appointment.

He will now work with spin bowlers such as Shakib Al Hasan, Nasir Hossain, Mehedi Hasan and Taijul Islam.

"It is an exciting opportunity for me, and I am looking forward to working with the Bangladesh spinners who I believe have what it takes to continue to make waves on the world stage," Joshi said to Wisden India.

"I have obviously seen plenty of Shakib Al Hasan and Nasir Hossain, and I have followed the progress of Mehedi Hasan and Taijul Islam with great interest.

"We have at least four or five practice sessions ahead of the first test.

"That time will help me get familiar with the spinners, and for them to also get used to me. 

"I think the key will be communication and to keep things open and honest. 

"I see plenty of potential in the spinners that have been doing such a stellar job for Bangladesh, and I will do everything possible in my capacity to help them develop further and do justice to their abilities."

Joshi was an accomplished left-arm spinner himself, appearing in 15 test matches for India and taking 41 wickets.

He also took 69 wickets in 69 one-day internationals.
