“If other senior bowlers are missing from the team, then I have to step up. I have done this previously for other teams that I have played for. I have come in place of Zaheer Khan, Dhawal Kulkarni and Ajit Agarkar while playing for Mumbai (in Ranji Trophy). I had to step up in that role. When senior bowlers are rested, I have to step up and fill that role to lead the pace attack,” Shardul Thakur said.
