Dundee boss Paul Hartley says his side only have themselves to blame after they were dumped out of the Scottish Cup by Rangers.
The Light Blues were rampant as they recorded an impressive 4-0 win.
Harry Forrester blasted Gers ahead inside 13 seconds and three second-half strikes from Jason Holt, Andy Halliday and Lee Wallace put the seal on Dundee’s demise.
Dark Blues boss Hartley was left distraught by his side’s sloppy start to both halves.
“I’m extremely disappointed with the manner of the start,” he said. “The last thing we said to them before we went out was make sure you have a good start to the game.
“We were a goal down after 13 seconds and what does to the home team, it just gives them a massive lift.
“We have got to be honest with ourselves and say Rangers totally deserved to win today and we didn’t perform.”
Rangers boss Mark Warburton watched his side put on the best display of his Ibrox reign – but still does not reckon it was enough to have their potential semi-final opponents running scared.
Warburton’s side will discover late on Sunday afternoon who they will face in the last four of the competition, with Dundee United winners over Ross County in the day’s second quarter-final one possible opponent.
But despite the emphatic nature of his side’s victory, the Englishman does not believe it will have intimidated their eventual Hampden adversaries.
“I don’t think anyone fears anyone,” he said. “If you’re in the semi-final of a trophy, who are you going to fear?
“Our job, whoever we face, is to do well. Don’t forget, it’s only seven and a half months since this team came together. All credit to them for the way they have applied themselves and they deserved today’s result.
“But they are a young side and teams in the semi-finals won’t fear anyone I’m sure.”
