The pacer from Vidharbha has picked 17 wickets from four Tests, including the three he took in the final match in Dharamsala today.
Commenting about the performance of Umesh in the series, Ganguly said, "To see an Australia team on the back foot against fast bowling is a great sign. Umesh, to me, is the find of the season. Hope he carries on the good form with the ball."
The Cricket Association of Bengal, where Ganguly is the president, also praised spinner Kuldeep Yadav on his impressive debut.
According to Ganguly, "He is young. He will learn. Credit should go to (coach Anil) Kumble for giving him an opportunity. End of the day it's the bowlers who will pick 20 wickets for you to win Test matches."
Ganguly, who is the ambassador for FIFA U17 World Cup in India, is happy to see Kolkata getting the final of the marquee event.
"It's great to see the final being played in Kolkata," he quipped.
