Pell was cleared earlier this year of child sexual abuse charges in Australia after spending 13 months in prison, and it remains unclear whether he will take up another role in the Vatican.

The Vatican announced the meeting between Pell and Pope Francis in a statement on the Pope's daily private audiences, but gave no details.

"It went very well," Pell told reporters on Monday in front of his residence just outside the Vatican walls.

Pell, 79, returned to Rome on September 30, just days after the Pope fired Pell's nemesis, Italian Cardinal Angelo Becciu, who was accused of embezzlement and nepotism. Becciu has denied all wrongdoing.

While Becciu was number two in the Vatican's Secretariat of State and Pell was economy minister, the two had a very stormy relationship.

Becciu told reporters the day after he was sacked about a meeting between Pell, the Pope and Becciu where Pell told Becciu, "You are dishonest", and Becciu replied: "How dare you!"

After Becciu was sacked, Pell said: "The Holy Father was elected to clean up Vatican finances. He plays a long game and is to be thanked and congratulated on recent developments." Pell said he hoped the "cleaning of the stables" would continue.

Becciu's lawyer has denied Italian media reports that his client sent money to Australia to help Pell's "enemies" while he was facing the sexual abuse charges.

Through his lawyer, the Australian man who accused Pell of sexually abusing him two decades ago denied Italian reports speculating that he may have been bribed to testify.

Pell's Australian lawyer, Robert Richter QC, called for an investigation "to track the money trail". He said it should include Italian and Australian investigators.

"If one is to give any credence to what has been alleged, then it is critical that all proper money-tracing exercises be undertaken," Richter told Reuters.
