Just as Hearts looked to be running out of ideas, Harry Milne delivered an inviting low ball for Tomas Magnusson to net the late winning goal against Hibs.
It left-back Milne's sixth assist of the season – the joint most in the Premiership.
The 29-year-old has blossomed as a Hearts regular this season and more than played has part in the dramatic derby win for the Premiership leaders.
For starters, Milne made 14 final-third entries – no played on the pitch made more – while his three dribbles were the most of any Hearts player.
Milne won 10 out of 14 duels, only Pierre Landry Kabore won more, while he won possession six times – again the most of any player Hearts player.
In terms of delivery, Milne's six crosses was also the biggest total for any Hearts player while his one chance created – which led to the goal – wasn't bettered by anyone in maroon.
Looking at the season as a whole, Milne's stats are impressive. His 156 passes played into the box (including crosses) is the sixth highest of any player in the league while his 36 chances created is the seventh highest.
Milne has delivered 51 successful crosses (including corners), the highest of any Premiership player, while his 15 chances created from set-plays is only bettered by Rangers' James Tavernier.
Milne's contribution will be vital for Hearts as they continue their push for the Premiership title.
