Dhoni retired from international cricket in August last year.
In an exclusive chat with Cricbuzz, Buttler said he loves Dhoni’s iconic six to win the World Cup and his bat twirling celebration thereafter.
"I love the shot of him hitting that six to win the World Cup and then he twizzles his bat around. That was all he gave you, it is probably the biggest moment in Indian cricket history and he still just pulls it off with such composure. I love watching him play," Buttler quoted.
"I like that about him, made me intrigued about him. It is quite amazing trying to think what he is thinking about, why is he not riding the emotions of the game. He always kept people guessing like that. I like the way he does things because they make sense to him. It doesn't look like he worries too much about what it looks like," he added.
Dhoni, who announced his retirement from international cricket in August last year, represented India in 90 Tests, 350 ODIs and 98 T20Is, aggregating more than 17000 international runs with 16 centuries.
He also has 634 catches and 195 stumpings (world record) to his name across three formats.
Commenting on Dhoni’s keeping, Buttler said: "As a wicketkeeper, those lightning-fast hands and reactions he has. Some of the positions he is in sometimes, technical coaches may say that is not quite right. The way his hands are almost moving back towards the stumps before he has caught the ball, it is quite amazing."
