Crystal Palace took a further step towards Premier League survival with a 1-0 victory over Burnley which extended the visitors' winless run to seven games. West Brom, who have gone 20 league matches without a win, have only scored 16 goals all season and they come up against a Brighton side that has failed to score in eight of their 11 away games.
