Burnley boss Sean Dyche was disappointed to concede four goals in their FA Cup defeat at Tottenham.
The Clarets struck twice away in London, but it wasn't enough.
"I don't know if we let it get away, they are a good side," Dyche said. "But when you're 2-0 up and you make mistakes like we did, it will be tough.
"It was just the details that really hurt us tonight. They supplied the details and we didn't. You can't get away with that as this level."
Burnley now face a blank weekend on January 24, but Dyche does not expect any far-flung warm-weather training jaunts.
"Maybe we'll go to Scarborough!" he joked. "Joking apart, I don't know what we'll do yet.
"We'll have to decide beyond that. Who knows if we'll benefit from that rest, there's no guarantee.
"There's no choice about it: we wanted to win, we didn't, so we move forward."
