The World No 1 will host the Swiss legend in his second exhibition event, Andy Murray Live, at the SSE Hydro in Glasgow on November 7.
The 29-year-old Dunblane star had some light-hearted advice for the 18-time grand slam winner.
Murray said: "Don't try the fried Mars bars. I tried one of them for the first time last year and it was horrific. Stay away from them."
The 2016 event raised £300,000 for Unicef, the children's charity which is again a beneficiary, and Young People's Futures, a Glasgow-based children's charity.
All proceeds will go to charity, with a second, local charity partner to be announced in the near future.
