Cathro praises Hearts' mentality after setting up huge Hibs clash
Hearts head coach Ian Cathro saluted his players for passing a serious test of character and securing a William Hill Scottish Cup derby.
A 4-2 extra-time replay victory over Ladbrokes Championship side Raith Rovers at Tynecastle earned Hearts a fifth-round home tie against holders Hibernian.
Hearts fell behind early on to Bobby Barr's deflected strike and failed to capitalise on some belated pressure to avoid extra-time after Rory Currie's first-half equaliser.
But Malaury Martin and Jamie Walker netted penalties either side of Ryan Hardie's equaliser, with Bjorn Johnsen making sure of the win, Cathro's second in seven matches in charge.
Cathro said: "There were emotions and attacks going on and the strongest man wins that test of being able to fight, being able to stay together and deal with the setbacks and stay strong.
"All those things created a really, really big test on the players to get through that and we did and I'm pleased we have that reward.
"It was tougher than we would have liked but sometimes that challenge is even better to have than being straightforward, because we have now surpassed it."
Hibs will visit Tynecastle in the cup for the second year running.
Cathro, who refused to comment on reports linking him with former St Mirren forward Esmael Goncalves, said: "It's a massive game, those are the games that all of us love the most."
