Emmanuel Adebayor headed Spurs in front in the 35th minute and then tapped in their third after a Chico Flores own-goal had doubled the visitors' lead.
The defeat means the Swans remain just three points above the drop zone .
Laudrup, whose side have now gone eight league games without a victory, said: "Again, great attitude, put them under pressure, had a couple of good chances...and then the first time they have a shot on target they score.
"But it's something that happens when you're a team that is struggling a bit. It's not our moment and things like that happen.
"I think we have to admit that we have some problems right now, we haven't won for quite some time, but on the other hand we just have to continue like this.
"I think the only thing we need is a success, that means a win in the league, and now we just have to move on."
