Pulis spent 28 games in charge at Selhurst Park, taking over from Ian Holloway in Palace’s first season back in the Premier League.
He kept the side in the top flight playing his brand of defensive football, but left days before the start of the 2014/15 season after not being backed in the transfer market by the club’s board.
After spending time out of the game, he was appointed West Brom manager on January 1 of this season, and went on to keep the Midlands side in the top flight.
He has started this season in fairly poor form, and he takes his side to Palace looking to pick up just West Brom’s third win of the season.
And there is a statistic which shines highly in his favour, having won six consecutive games against teams he used to manage.
He has lost only one of eight Premier League games against his former sides, and in the six consecutive victories, there have been five clean sheets for the team he is currently in charge of.
West Brom will be hoping this statistic continues this weekend, and Pulis’ knowledge of the Palace squad could play a vital part in him picking up another three points against one of his former sides.
