Heaping praise on Dhoni, Ganguly said the wicket-keeper batsman's record has been fantastic as he has led the country to the World T20 title and has proved it again for Chennai Super Kings, leading them to the title twice (2010 and 2011).
"Overall Dhoni is the best T20 captain now. Dhoni's record in this format is fantastic. He has led the country to the World T20 title. He has made Chennai Super Kings champions twice as captain. And Gambhir is only captain of this year's IPL winning team (Kolkata Knight Riders). So I feel the time has not come to compare Gambhir with Dhoni as far as captaincy is concerned," Ganguly said.
Though he admitted that Dhoni wasn't at his best on Sunday, Ganguly said it looked like the Chennai Super Kings skipper was under pressure when he went out to bat.
"I don't think his captaincy today was as good as in other games. He seemed under pressure as captain and when he went out to bat. I did not like his body language," Ganguly said.
Ganguly further added saying the Chennai skipper did disappoint him with his move to go with offies when both the right-handed batsmen were at ease and feels Dhoni should have gone for a left-arm bowler.
"When two right handers were playing so well, Dhoni continued with offies. I found it surprising. He should have used a left arm bowler," he said.
When asked Gambhir can replace Dhoni as Test captain following his successful stint as KKR captain, Ganguly said Gambhir also has not done well in his last eight Tests.
"As a Test player, I feel there is a question mark over Dhoni. But Gambhir has also not done well in the last eight Tests."
"But obviously, Dhoni's case is different. He is the incumbent captain. So he has got the backing. But if Dhoni does not play well, this is a possibility, but not in the near future," he added.
