Hearts coach Gary Locke admits Saturday's William Hill Scottish Cup final against rivals Hibernian at Hampden as the biggest Edinburgh derby of all time.
It is the first time the two capital clubs have played each other in the Scottish Cup final since 1896.
"I have been involved in some massive games as a player but certainly this is the biggest as a player or a coach," the former Hearts skipper told Press Association Sport.
"It has never happened in my lifetime and possibly may never happen again in my lifetime, that shows you the magnitude of the game.
"After we managed to beat Celtic in the semi-final everyone knew the final would be against Hibs and the whole city is buzzing about it.
"It is two massive clubs with huge fan bases all going through to Hampden to have a great day and hopefully it is us who are celebrating at the end."
