The prospect of a second day-night Test being added to this summer's Ashes schedule has captured the imagination of England wicketkeeper Jos Buttler.
With Perth's hopes of hosting the fifth Test from January 14 in doubt due to WA government border restrictions, several replacement venues are being mooted including Hobart's Blundstone Arena or Canberra's Manuka Oval.
Another alternative is hosting a day-night clash at the MCG, which would give broadcasters a chance to fill the prime-time evening slot on the east coast normally utilised during the Perth Test.
Adelaide Oval is set to host a pink-ball match in the second Test of the series from December 16 and Buttler says another day-night game on the schedule would be special.
"Having watched the game at Adelaide, it's a great occasion," Buttler said.
"If there's one place in the world where day-night Test match cricket sort of seems to work, it looks like it's Australia that's the best I'd say.
"It would just make for an incredibly unique Ashes series. It's already unique. It's already different.
"The traditionalists would love it to be probably five red-ball games but if that had to happen, or that was what was in the best interests of the games going ahead and running smoothly, then you'd have to be open to it."
Buttler's enthusiasm for pink-ball Tests is perhaps unlikely to be shared by England's chief decision makers given Australia's sensational day-night record.
Australia have won all eight day-night Tests they've played, including two by an innings and a 120-run victory in the 2017-18 Ashes.
England have, by contrast, played three day-night Tests away from home and lost all three by healthy margins.
