Swansea City boss Francesco Guidolin was frustrated with their 1-1 draw against Crystal Palace.

Swansea are now unbeaten in three games under Guidolin.

But Palace's equaliser dragged the home side nearer the relegation zone, with Swansea now in 16th place with 27 points from 25 games.

"It is a problem at the moment and we must understand what is better for our team," Guidolin said.

"That will be not having set-pieces coming against us, but it's not possible because in the Premier League all teams are very strong in set-pieces.

"We also had two big chances to score from offensive set-pieces and I think we have to work to improve this situation.

"But there is no need to be worried, we have to try and improve it and do more work on the training ground."

Reflecting on the battle at the bottom, with Newcastle's win over West Brom taking them to within three points of Swansea, Guidolin said: "The table is better than it was for us three weeks ago, but we must take points every weekend.

"We should have won this game but it is one point and we must now look to next Saturday."
