Natrajan got his nick name as Yorker king and he is highly effective with Bumrah which adds deadly combo to the pace bowling. Saini os good bowler but inconsistent makes them to be on the lower side and it affect team momentum when they are playing against best teams in their own ground.
I have a feeling that Natarajan would make an excellent pace bowling duo with Jasprit Bumrah. Saini is too inconsistent, and he always attempt to bowl as fast as possible, rather than trying to maintain good line and length. He is very expensive, especially when playing against good teams such as England and Australia. And the less talked about his attitude, that better. I hope no one has forgot the beamer he bowled to Stoinis during the IPL and his refusal to apologize.
