Mane will face Ronie's former club Barcelona in the first-leg of the Champions League semifinal on Wednesday night.
On the Brazilian, he said: “Ronaldinho, for me, was my hero. I really love watching him play here. For me, is a dream come true.
“I would love to play against him but tomorrow he's not here - maybe [that's] an advantage for us!
“I still love him and he's still my hero forever."
Asked why he had taken such a liking to the former Brazil international, Mane replied: “His skills, smiling for sure.
“Maybe I'm not smiling on the pitch… people think I'm angry but I'm not like this!
“I would love to have his smile but I think we are not similar on this side!"
