Ronaldinho's proposed transfer to AC Milan has stalled after the Serie A side failed to agree a fee with Barcelona.
Milan chief executive Adriano Galliani admitted preliminary discussions had not been successful.
'Yesterday we had a conference call but the figures have not been right,' Galliani told Sky Italia after Milan's 5-1 win over Reggina.
'Maybe Ronaldinho won't come.'
Robert De Assis, Ronaldinho's brother and agent, has agreed personal terms with the Milan club but there is competition from city rivals Inter and Barclays Premier League outfit Manchester City.
