Cameron Jerome believes Crystal Palace's new-look side have the ability to "hurt teams" this season.
Ian Holloway's side were chasing shadows from the outset at Selhurst Park, where the margin of victory should have been much larger than 2-0.
The Palace boss was left particularly disappointed by the display of his recent arrivals, who he gave a dressing down after the match.
"Swansea are a very good footballing side and you have got to give them credit," the on-loan Stoke striker said.
"It is all a new process for us, we have got so many new players and stuff like that.
"It is just finding the right ingredients and getting that understanding together. We have got to do that sooner rather than later.
"We know we can play a lot better than that, but sometimes you have got to hold your hands up and say you were beaten by the better side.
"We have got to move on. If you dwell on things in this league, you are chewed up and spat out.
"Maybe we showed them a little bit too much respect and sat off them. You have got learn to cut out the mistakes as soon as possible.
"If we can do that and make sure we give our all, I am sure we can hurt teams here. It is just about us gelling together. That is not an excuse but all these little factors do add up."
Jerome was one of a number of attacking players brought in over the summer, following Wilfired Zaha's departure to Manchester United and a long-term injury to last season's top scorer Glenn Murray.
"The gaffer brought him in and he is a good player," Jerome said of his fellow frontman.
"I don't think he had a fair crack of the whip at Arsenal and he works very hard for the team.
"He is unselfish and brings other people into play. We can work that and he can be a key focal point for the team.
"The more you play, the more you get an understanding. Sometimes you hit it off instantly but sometimes it takes time to click. The manager has got competition for places."
It continues the Swans' hectic schedule of late - one that has produced a momentous week for the club.
"It was a very professional display," left-back Ben Davies said. "It was a performance that deserved all three points. There were never any issues of fatigue being a problem for us.
"The manager made five changes to the starting XI, but we have a good squad of players and everything is put in place for us to recover from games like Valencia and be ready for games at the weekend.
"We have a strong squad. We have players the manager can chop and change, and that's great for the team. I think that really paid off for us.
"We always go onto the pitch looking to be at our best from the first whistle, and that's what we did.
"On top of that, we prevented them from creating any real chances, so that was very pleasing. It's been a very good week for us."
