John McGlynn said he was "absolutely delighted" after watching his 10-man Hearts team recover from a goal down to beat Inverness CT on penalties to reach the Scottish League Cup final.
New loan signing Michael Ngoo levelled for Hearts at Easter Road after Andrew Shinnie had put Inverness ahead.
And after extra-time Hearts held their nerve to win the penalty shoot-out 5-4.
"It was exciting coming here for a semi-final but to go to Hampden will be a special occasion," said McGlynn.
"It will mean everything. It is absolutely amazing.
"I came back to Hearts to be involved in semi-finals and finals and within six or seven months we are going to Hampden for a cup final so I am absolutely delighted.
"It's something to look forward to.
"My wife and my daughter were here today and they will be delighted that their husband and father is going to be a happy chappie tonight."
Inverness's top scorer Billy McKay had a gilt-edged chance to win the match but opted to control the pass from Shane Sutherland instead of side-footing the ball home from six yards.
That was a huge let-off for the Tynecastle side playing at the home of their rivals, Hibernian, and, even with 10 men because of Scott Robinson's sending off in the 77th minute, they hung on at 1-1 in extra-time to take the semi-final to penalties.
"The guys had to work extremely hard here today. We came up against an Inverness side who were flying, top goalscorers in the SPL and for the majority of the game we kept them very quiet.
"There was one one-v-one early in the game and [goalkeeper] Jamie MacDonald did exceptionally well and later on they had a two-v-one and from their point of view they mucked it up.
"We had to make some last-ditch tackles and a great save but over the piece I thought we played some excellent football.
"I thought we thoroughly deserved to win, albeit when it comes down to penalties it is a bit of a lottery.
"Great credit to the players to play with 10 men for so long - brilliant character and spirit from the team to come back from a goal down and take the game right to Inverness.
"I'm delighted for big Michael to get his goal and for the whole team and fans and everyone here who played a big part today."
With the cost-cutting at the club, the Hearts team had a youthful complexion, but the manager was thrilled to see how well his players coped with the pressure.
"The young guys have got great ability - [Jason] Holt, [Callum] Tapping and Robinson in the middle of the park," McGlynn told BBC Radio Scotland.
"It was a bit of a downer for Scott to get sent off but his play was magnificent before that.
"Jamie Walker, Fraser Mullen at right-back and big Michael did exceptionally well.
"We were brave enough to put them in and the guys repaid us and I thought the football we played was excellent at times."
