Hearts boss Robbie Neilson wants his side to "move on" form last weekend's Edinburgh derby success and realise the magnitude of the next one.
The Jambos will face Hibs again this Saturday at Hampden as the Edinburgh sides battle it out for a place in the Scottish Cup Final.
Neilson's men defeated their rivals 3-1 at the weekend.
Despite The Hibees taking the lead after just five minutes, an Andy Halliday double and Stephen Kingsley strike make sure the three points stayed at Tynecastle.
But it is much more than three points at stake this weekend, and the Hearts boss has insisted that his team need to be at their best.
Speaking during a press conference earlier today, the Jambos gaffer said: "We've trained well the last couple of days so it's all about the build up to the big game.
"Obviously all eyes were on last week and it was important we got the result in that, which we did, but it's important that's put to bed and we move on and do the same thing again in the Cup."
Neilson was then asked if he can take any satisfaction from his achievement so far this season.
He said: "I'll tell you probably about half three on Saturday if we can get through the cup game." He said.
"These two games are almost season-defining for us. We've had a good season so far, but we've got an opportunity on Saturday to make it a great season.
"It's going to be difficult. Yes we got a good result at the weekend against Hibs but it's a different environment, different pressure and we need to make sure we're ready for that.
"I think it's important they realise it (what's at stake), which they do. We tried to keep them focused on the league game on Saturday, which they managed to do and got the result.
"Once it was over it was all eyes on the following Saturday and making sure we're ready for that because it was good to win that derby, but we've got one seven days later, and after that there's not another derby for four or five months so we want those bragging rights."
The Hearts boss also confirmed that his side have no additional injury worries as they prepare for Saturday's clash.
Neilson added that defensive midfielder Cammy Devlin is back from injury and will be available for selection at the weekend.
