5. Padmakar Shivalkar

Padmakar Shivalkar, another example of being born at the wrong timeline of the Indian Cricket Team, was possibly the finest slow left-arm orthodox who did not represent India. Padmakarhivalkar was unquestionably better than many Indian cricketers, taking 589 wickets at an astonishing average of 19.69 in only 120+ matches. 

He could pitch the ball at a particular length for extended periods, making him a captain's fantasy. As a typical finger spinner, he spun it prodigiously anytime he gave it a proper tweak. However, just like Rajinder Goel, Shivalkar was fighting against the likes of Bedi, Venkataraghavan, Prasanna, and Chandrasekhar, so, unsurprisingly, he didn't have much of an opportunity to wear the Blue cap.
