A goal in each half – both of them looking avoidable – sent the Swans crashing to defeat at Crystal Palace after an unbeaten run of five games in all competitions.
For the second time this season, the Swans were undone in London thanks to two sloppy goals.
And the Swans captain insisted that the Swans can bounce back but they must avoid repeating these mistakes in future games.
Two home games beckon for the Swans this week – Derby and Burnley are both at the Liberty – and Monk wants to take those chances to remove the thoughts of Palace.
''Palace haven't worked for them at all. We have given them a 2-0 lead and then left ourselves with a mountain to climb.
''It's a difficult one,'' Monk added when questioned on who was at fault for the first goal.
''I don't know who went with the man at the front post, but you'd have to say he's done his job by not letting his man head it.
''Dorus is expecting a flick and then it just goes straight in. It's not a good goal to give away.
''I'm not blaming anyone,'' Monk said. ''I don't know if Dorus saw it late, but it wasn't particularly well struck and I was quite surprised to see it go in.
''But, at the end of the day, we haven't performed and I think the result went the right way.
''I don't think Palace are a great side — we've come up against better already this season — but we didn't impose ourselves and we can't complain about the defeat."
Monk was also adamant that his side should have had a penalty in the second half when the score read just 1-0 to Palace
''It was a definite penalty,'' Monk insisted. ''The lad's got his hands in the air when the ball hits them. If that had gone our way things might have been different, but it was disappointing that we didn't play our game after we went 2-0 down.
''We played into their hands and we're all disappointed because we're bad losers.''
