Swansea produced the perfect performance in front of new manager Paul Clement as goals from Alfie Mawson and Angel Rangel sealed a vital victory over Crystal Palace.
The visitors made their dominance pay when Mawson headed in Gylfi Sigurdsson's free-kick in the 42nd minute but that goal was cancelled out in impressive fashion when Wilfried Zaha volleyed home in the second half.
But substitute Rangel ensured Clement, who watched from the Selhurst Park stands on Tuesday, witnessed a win on the day he was appointed as the Swans boss on a two-and-a-half year deal.
