The South African leg-spinner, who joined Daredevils in the 2014 season, wants to make an impact as a valuable spinner for his team.
"It's hard, T20 cricket and also the ODIs where five fielders are inside the inner circle. But spinners play a key role in T20. They have a lot to give in the limited-overs game and it makes them better bowlers. The modern-day game helps us perfect our cricket more than what it was before," Tahir said in an open session organised by Delhi Daredevils.
The Pakistan-born player, who has represented South Africa in 16 Tests and 38 ODIs, is ready to adapt to 'changing times' as a spinner.
"The art of spin is very much alive and you see that in Test cricket. But I still think even in Test cricket you cannot be a classical spinner, say what you were 20 years ago. Cricket has obviously changed.
Tahir acknowledges the quality of Indian batsmen against spin bowling and stresses the role of variety in a spinners life.
"There are a lot of left-arm spinners from India who have had a lot success, so for me all the spinners have a big role to play in cricket.
