Hearts ended Celtic's 69-game unbeaten domestic run in stunning fashion with a 4-0 hammering of the Ladbrokes Premiership champions at Tynecastle.
A much-changed home side surged into a two-goal interval lead as 16-year-old Harry Cochrane fired in his first goal for the Edinburgh club in the 26th minute before former Rangers striker Kyle Lafferty added a second with a fine finish nine minutes later.
Attacker David Milinkovic capitalised on more poor Celtic defending to grab a third goal three minutes after the restart, before adding a 76th minute penalty to put the finishing touches on a remarkable and historic afternoon.
