Bronzetti - a renowned FIFA agent and the man behind most of the big transfers between La Liga and Serie A - had dinner with Milan vice-president Adriano Galliani and Ronaldinho's brother and agent Roberto de Assis on Wednesday.
"Roberto de Assis was travelling to London and was only in Milan for a stopover, that's why we went to dinner together.
"If we wanted to hide ourselves and do a deal we certainly wouldn't have gone to restaurant Giannino."
Bronzetti denied the suggestion that Ronaldinho's move to the San Siro could depend on the Rossoneri securing a Champions League place.
But he did admit that several others clubs are also in the hunt for the 28-year-old's signature.
"The Champions League doesn't come into it at all," he added.
"Players come to Milan even if they aren't in the Champions League.
"But there's no lack of offers. There are three or four clubs interested in him - Chelsea definitely, and also Liverpool."
