The Swans were not too worried by the Blues during the first half before Oscar and Frank Lampard (penalty) hit the back of the net twice just before the break at Stamford Bridge.
The loss did nothing to change Swansea's position of ninth but Laudrup felt they could have possibly gotten something out of the contest if it wasn't for that lapse in concentration.
"I think the first 40 minutes, I don't recall any big Chelsea chance in front of goal," he told Sky Sports.
"Of course you know when you play Chelsea, especially away, it's a great side, very talented players, especially the ones in the second line just behind the striker.
"But having said that, 40 minutes not suffering at all and then suddenly in five minutes losing a ball in the midfield, one, two, three (passes) and it's a goal and two minutes later a one-two and a penalty and another one.
"That was too much for us I think, one goal you can cope with that but two goals in just two or three minutes just before half-time, it was too much.
"We came out in the second half, we were still a little groggy in the first 10 minutes, they could have scored a third one, then we came back into the game.
"We played well until the last third but we just missed the last pass or the finish."
