Salah scores in 7th straight game
Victory continued Swansea’s improved form under Portuguese manager Carlos Carvalhal.
Since he joined the club at the end of December with Swansea bottom, it has won five league games and lost only two.
In contrast, West Bromwich Albion’s change of manager in the same month has not paid off.
Alan Pardew’s job appears to be under greater threat than ever after a 1-0 defeat at Watford.
Albion has now won one of 15 league games since Pardew took over at the start of December and is seven points adrift at the bottom of the table.
Watford captain Troy Deeney was sent clear by Will Hughes to score the only goal.
“The players gave me everything today and I cannot ask for more than that,” Pardew said.
“It is tough but it isn’t about me, it about West Brom and it is tough for the fans and the players.”
Stoke City stayed second-bottom, but earned a valuable point in a 0-0 draw at Southampton.
Burnley supporters must have despaired when their team went a goal down at home to Everton. Sean Dyche’s team has never won a Premier League game after falling behind.
This time it did, however, celebrating Dyche’s 250th game as manager by winning 2-1 with goals from Ashley Barnes and substitute Chris Wood.
Everton captain Ashley Williams was sent off four minutes from the end for a wild swipe at Barnes.
In Sunday’s other match, Arsene Wenger’s struggling sixth-place Arsenal visits mid-table Brighton & Hove Albion.
