Nehra had joined RCB last season as the bowling coach, and is the only one, apart from Kirsten, among the coaching staff from last season to still be part of the set-up. The left-arm pacer has represented India in 17 Tests, 120 ODIs, and 27 T20Is. His last international match was a T20I against New Zealand in November 2017.
In a statement released by the franchise, Nehra said: "I had the privilege to join the coaching team of RCB last season and feel very passionately about the team. I want to thank the team management for considering me in a leadership position with the franchise and look forward for the successful seasons ahead."
Sanjeev Churiwala, the RCB chairman, was hopeful that the team of Nehra and Kirsten would help RCB deliver a good performance.
Kirsten, like Nehra, had joined the franchise as a batting coach last year and was appointed coach and mentor of the team on August 30. The South Africa batsman replaced Daniel Vettori, who had been the coach of the franchise since 2014.
RCB haven't yet won the IPL, though they have been the losing finalists three times, in 2009, 2011 and 2016.
