Ryan Hardie
Scott Pittman has come through the lower leagues with Livi but is making a real impact at the top level.
The dynamic midfielder makes another powerful run deep into the Hearts half before setting up Ryan Hardie for a fine stabbed finish past goalkeeper Zdenek Zlamal.
The Hearts fans are already streaming out the stadium.

Dolly Menga has certainly made an impact in the last couple of minutes.
Having got Arnaud Djoum sent off, the Angola striker weaves past three Hearts defenders, changes direction again and rolls the ball past goalkeeper Zdenek Zlamal.

It's all going Pete Tong for Hearts as Arnaud Djoum is sent off after picking up a second yellow card.
The midfielder clatters into the back of Dolly Menga.
It is more clumsy than deliberate and the yellow card looks a bit harsh.
Livingston 0-0 Heart of Midlothian

Quote MessageWithout a question, it's a penalty. He's late. Anywhere on the pitch when you're that late it's got to be given. Sometimes referees don't give those ones.
Craig Halkett
Craig Halkett fires the ball down the middle as Zdenek Zlamal dives to his left and Livi are in the lead.
Fully deserved.

Zdenek Zlamal crashes into Craig Halkett, cleaning out the Livi centre-half as they go for a high ball.
Referee Nick Walsh shows Zlamal a second yellow card then a red.
As the stadium wonders where the first yellow had come from, the official realises his mistake and ushers the goalkeeper to the goal line to face the penalty kick.

Quote MessageYou very rarely see Livingston lose a second ball - they're tigerish in the tackle, they win it back and double up. It's great to watch at times. It's great teamwork, they tackle for each other and they've got great aggression
Livingston 0-0 Heart of Midlothian
Great chance for Ryan Hardie to break the deadlock as the striker races deep into the Hearts penalty box.
But the on-loan Rangers man flashes his cross-come-shot across the face of goal and wide.
Livingston 0-0 Heart of Midlothian
Livingston manager Gary Holt makes his first change, with former Hearts midfielder Scott Robinson replacing Nicky Cadden.
Livingston 0-0 Heart of Midlothian
Hearts made an impressive start to the second half, but Livi have weathered that initial storm and are again looking the more likely to break the deadlock.
Livingston 0-0 Heart of Midlothian
Christophe Berra is sent sprawling chest first into the artificial turf and Livi striker Dolly Menga goes into the referee's book as that push is deemed to be the latest in a series of fouls.
Livingston 0-0 Heart of Midlothian

Quote MessageZlamal is a little bit erratic at times. Certainly from crossed balls, slapping the ball instead of punching it. But he's made some fantastic saves so far tonight
Livingston 0-0 Heart of Midlothian
Zdenek Zlamal has made a couple of fine saves, but the Czech goalkeeper has his moments of madness and a delayed clearance followed by a miscued pass put Peter Haring in trouble and the blushes are saved as the defender is fouled.

Quote MessageHaring has gone into the backline - it's almost a back three. It's almost the same shape as Livingston, even a 3-4-3, to try and cause Livingston problems. There's no question Craig Levein would not have been happy about Livingston's dominance

Quote MessageGood start from Hearts and exactly what they needed. It looks like Clare is going up with MacLean to play as a second striker. It's certainly caused Livingston problems
Livingston 0-0 Heart of Midlothian
Hearts midfielder Arnaud Djoum goes into the referee's book for a stray elbow into the face of Keaghan Jacobs.
Livingston 0-0 Heart of Midlothian
Hearts goalkeeper Zdenek Zlamal comes out to head a long ball clear outside his penalty box and is happy to see Keaghan Jacobs' attempt to lob from range into the empty net go high and wide.
Livingston 0-0 Heart of Midlothian
Sean Clare makes an immediate impact.
Steven MacLean flicks on a high ball and the midfielder races through the middle only for Liam Kelly to block the shot from close range after the goalkeeper rushes off his line to the edge of the penalty area.

Quote MessageIt's difficult to pose a threat against Livingston. They are such a well-oiled unit now. It's very difficult to impose yourself and play against. The key is to go forward very quickly and catch them out - because that's when they're out of shape
Livingston 0-0 Heart of Midlothian
Hearts get the game under way and there is a change to their line-up.
Sean Clare had been dropped to the bench, with Callumn Morrison in his place at the start.
But the former Sheffield Wednesday midfielder is back in the side for the second half.
