Daniel Stendel believes Hearts' stunning win over Rangers can inspire his side to repeat the trick at Celtic Park.
The Jambos boss secured a 2-1 victory, his first for the club, over Steven Gerrard's team in January and can do so again when the teams meet in the Scottish Cup quarter-final.
First, the Gorgie outfit - sitting one point behind Hamilton at the bottom of the table - have to face league leaders Celtic, who have lost only two domestic matches this season and just one at home.
However, boss Stendel takes encouragement from the win over the Ibrox side.
"It showed that we can win games against teams from the top of the table," he told Hearts TV.
"We need a really good day but what I can promise is that we will try to win.
"They have the best offence in the league and we need to put them under pressure and we need to take our chances and, if we can do that and defend well, I think we have a good chance."
On the cup draw, he said: "First, a home game is good.
"When you want to win the cup you need to win against every team. They are one of the best teams but we showed in the past that we can win.
"I think it will be a good fight and I like that we play again in Tynecastle."
