Paul Hartley sees no reason why Dundee can not go all the way in the Scottish Cup after they beat Aberdeen 2-1.
The Dens Park men were toiling under Dons pressure after Thomas Konrad had scored at both ends, but David Clarkson scored for the eighth game in a row with a dramatic late winner.
"Why can't we? We've got the players, we've got a good mentality about us," Hartley told BBC Scotland.
"You need luck in the cup and we got it today."
German defender Konrad had given the Dees an early lead only to direct Niall McGinn's cross into his own net.
Goalkeeper Scott Bain pulled off a string of saves, including one from McGinn in the dying seconds, and Clarkson stunned the Dons in time added on.
"I think we were looking to settle for a draw there because we weren't at our best, but credit to Aberdeen they put us under so much pressure today. We had to really dig deep for that result," said Hartley.

"When you've got a man in Clarkson on form it just needs one chance and the composure he showed was fantastic, but up the other end my young goalkeeper Bain is absolutely outstanding.
"We're through, it's all about getting through to the next round. I think it's about time we had a little bit of luck and I'm delighted for my group of players.
"I thought it was a good cup tie. Credit to Aberdeen they're a good team, their movement caused us a lot of problems, but my players dug in today, I thought they were terrific."
Clarkson echoed his manager's sentiments that Dundee can lift the trophy for the first time since 1910, and Hartley is delighted with the return from his striker.
He said: "He's got experience and he can score goals.
"He just needed to get a team and get his fitness up because I know his quality and he's producing week in, week out for us just now."
