Docherty praised his team’s “mentality, resilience and character” after the game, an understandable comment given the circumstances.
Dundee are currently without injured defenders Ziyad Larkesh, Antonio Portales, Joe Shaughnessy, Jordan McGee and Billy Koumetio.
They have struggled for defensive consistency all season and the derby win was only their second clean sheet this season.
A series of last-minute blocks continued as the second half progressed, but Ethan Ingram’s goal prevented United substitute Ruari Paton, who had arrived on loan from Port Vale hours earlier, from scoring on his debut. There was nothing more impressive than the line. .
Whenever the defense was breached, goalkeeper Trevor Carson provided an answer, but Christian Trapanovski’s shot in stoppage time hit the post and rebounded.
“You could see the mentality, resilience and character of the team to get the shutout and get a clean sheet until the end,” Docherty said.
“If you think about it, given that we have five centre-halves, I think that performance speaks volumes. We have good players and we are very good at counter-attacking.”
“They put pressure on us, but our players withstood it.”
Winner Murray epitomized Dundee’s energy, leading the press from the front and providing a near-constant goal threat during an impressive first half that started with the decisive goal.
The former United and Ross County striker echoed the manager’s views on the players’ work rates.
“We gave it our all,” the 33-year-old said. “I feel great, I’m just excited to get the win.
“My old legs were tired at the end, but it was worth it. I’m really happy and looking forward to the next round.”
