Kilmarnock assistant manager Jimmy Nicholl was thrilled with the composure shown by Paul Heffernan as they striker bagged a brace in the Scottish Cup win over Inverness CT.
The Irish striker was named on the bench for the game and only took to the field after his fellow countryman Cillian Sheridan pulled up injured.
And the 31-year-old made the difference by drilling home the opening goal before a cheeky back heel ensured Killie’s progress to the quarter-finals.
Nicholl said: "We knew it was going to be difficult because of the way they have been this season and what we had on the park, with the inexperience.
"The manager had a decision to make and it turned out to be the right decision to stick with the young lads, Barbour and Gros and O'Hara.
"They did really well. I thought Willie Gros was excellent up front, O'Hara's composure, and Barbour's willingness, and then the attitude of the senior players who might have been disappointed they didn't start.
"Heffernan got two goals coming on and showing a wee bit of composure, and everything went right for us on the day.
"It just shows you how substitutions go for you accidentally and it has worked out for Heffernan, but there is no getting away from his composure for the first one and his quick-thinking for the other one."
