The Brazilian has claimed that it was the England goalkeeper's tactics that led to him missing his penalty in their international friendly on Wednesday evening
Hart made a fine save to deny the Brazilian from the spot, which helped England to their first victory over Brazil in 23 years as the English Football Association celebrated their 150th anniversary at Wembley.
The Brazilian playmaker put his shot to the left of Hart, and Ronaldinho told reporters: "Normally I don't aim for that corner.
"The goalkeeper deceived me and I ended up missing the penalty."
Goals from Wayne Rooney and Frank Lampard cancelled out Fred's second-half strike, and Ronaldinho admitted his side's lack of match fitness cost his team.
"We knew the difficulty of playing against a team that is nearing the end of their season," he said.
"In Brazil, some players are only just starting their competitions. I've only played one game this year."
