Cardinal Becciu has denied the allegations.
On Monday,lawyer Viv Waller,who represents the man who at trial in 2018 accused Cardinal Pell of sexually assaulting him in the 1990s,said she had seen the latest reports but rejected any suggestion that her client was connected to the allegations.
"My client denies any knowledge or receipt of any payments,"Ms Waller said.
"He won't be commenting further in response to these allegations."
Cardinal Pell's barrister,Robert Richter,QC,has called for an international investigation into the reports. Mr Richter told theAustralian Financial Review he wanted to"make sure the money trails are followed properly".
"I am treating these reports as requiring a proper investigation by all fiscal authorities to track the money coming to Australia,"he said.
