Scotland head coach Matt Williams is relishing the prospect of pitting his wits against his mentor when the Barbarians arrive at Murrayfield on Saturday.
Former Australia coach Bob Dwyer is leading the Baa-Baas on their summer tour which will also include matches against Wales and England.
Williams has worked under Dwyer, who guided Australia to World Cup glory in 1991 against England at Twickenham, with the Wallabies before taking over his role as coach at New South Wales Warratahs in 2000.
The Scotland coach is still looking for his first win in charge of the team after an RBS 6 Nations whitewash earlier this year.
But Williams insisted he would never have become an international coach without the help of Dwyer.
He said: "The Barbarians are what I consider a magnificent team and it is an honour to coach against them, and to coach against Bob Dwyer. He is a mentor of mine.
"I certainly would not be coaching at the top level without Bob and without his support as I was coming through as a coach.
"I know they will come out to play in the greatest tradition of Barbarian rugby so it will be a fantastic afternoon.''
Williams candidly admits he faces an arduous task in trying to reform Scottish rugby with his vision of 'Fortress Scotland', in which he wants all internationals to play for the three professional teams north of the border.
And although he has named three England-based players in the starting line-up for the game against the Barbarians on Saturday he has heaped praise on several Scots for pledging their future to Edinburgh, Glasgow and Borders Rugby in recent weeks.
Simon Taylor, Mike Blair, Tom Philip, Scott Murray, Ally Hogg, Chris Paterson, Nathan Hines and Bruce Douglas have accepted new terms at their respective clubs, while Andy Craig has quit Orrell for Glasgow Warriors.
Williams added: "It's been uplifting to see the players staying in very difficult financial times and players making real sacrifices in their contracts to stay and play in Scotland.
"To me, that is an incredibly uplifting statement - that these players have stayed when they have taken a reduction in pay.
"I think there is due reason for praise and it also shows the commitment the players have to Scottish rugby.''
