Swansea manager Roberto Martinez:
“It was a very good performance and to be able to score four goals against a side in a very, very good moment, speaks volumes of the performance.
“We knew the start of the game would be pivotal tonight. We knew Preston were going to be fresh and we had to start the game with a very high tempo.
“It’s great to see that we keep improving and keep getting better. We always planned to peak in January.
“It’s a long way to go, but we can get better.”
Preston manager Alan Irvine:
“The best team won without question.
“It was without doubt the worst performance of the season, but credit to Swansea, they were a fantastic team.
“We didn’t pass the ball well enough all the way through the game and we conceded some poor goals.”
