Bhuvaeshwar Kumar is a club standard bowler. Of course he will learn a lot from a world class bowler like Dale Steyn. However, Kumar should follow the example of Wasim Akram followign Alan Davidson to become even a superior bowler than his guru. Kumar is useless as he will be learningn for ever without reaching the standard of Steyn. There is no point in constantly admiring a Nobel Prize winner. You must try and become one. This is what the scientist Sir C.V. Raman used to tell everybody.
