Livingston play Hearts at the Energy Assets Arena this evening in the last of the Petrofac Training Cup second-round ties.
John McGlynn’s men go into the match on the back of a 2-1 home victory over Cowdenbeath on Saturday while Robbie Neilson’s team won Sunday’s Edinburgh derby by the same score.
Livingston beat Queen of the South 4-3 at Palmerston after extra time in round one of the competition while Hearts overcame Annan 3-1 at Tynecastle.
Former Hearts striker Gary Glen, now with the West Lothian club, said: “We are confident and believe in ourselves. We are not here to make up the numbers – we are here to win.
"You want to get a good run in any cup you are in. It is one we are excited to be in - it should be a good atmosphere and a big crowd."
Rangers, Peterhead, East Fife, Falkirk, Morton, Alloa and Stranraer are already through to Thursday afternoon’s quarter-final draw.
